Anyone know where I could find a cheap set of 202 heads or what engine they come off of and maybe I could find it in a junk yard or something..Thanks for your help.

 

Exactly what are you trying to achieve? Most likely a set of new inexpensive Vortec 1.94" intake heads will out perform any 2.02" heads you find in the junkyard.

 

"202 heads" is what olds farmers say when they don't actually know what they're talking about.
Please don't fall into that trap!

 

Lol no I do know what I am talking about so thanks for the 2 cents .. I only said 202 instead 2.02/1.60 heads or said that I was looking for 2.02 intake and 1.60 exhaust heads . becase thats what they are called 202 race heads .. and to answer the other guy the set up I am going for the vortecs isn't what I am looking for but thanks I just can't think of what engine had the 202 heads on it from factory ..So please I am not looking for anybody (what I think you should do ) just if you knew the answer to my ? would be great thanks agian ...

 

No, you have absolutely no idea what you are talking about, and it's readily apparent by your post.
Don't try to brag on here to us about your knowledge when you're asking a question, you won't get anywhere with that attitude.

That's like saying you're looking for Camaro's with a 400cid engine. That's a silly question. Anybody could put a 400cid into a Camaro, but is that really what you want? Or do you want a "fast" Camaro? Get my gist here?
2.02" intake valves do not make for good castings. Also, I think 2.02 intake valves are almost unheard of stock (ie. quite rare), and the few that did have it aren't even that good to begin with (anymore).

So back to square one, do you want to go fast, or do you want to brag about having 202 heads to the hillbillies at ol' joe's farm? I can throw some 2.02 intake valves into some 187 heads and you'll be good to go

 

Now like I said what I am looking for was did anyone know where I could get them cheap or had a Idea or knew the year(s) that they were from factory ... its that easy not tring to be rude in anyway just wanted to know that if you don't know great if you do well thank you but for your other 2 cents I really don't need but thank you anyway.. they came out of the factory sometime in the mid 60's I do know that but not what car thats what I was tring to find out .. And in no way I was trying to brag about what I know cause if I knew everything there was to know I woulnd't be on here asking questions and or reading other peoples post .. I just don't care for anyone to tell me I am some stupid farmer that dosen't know what he is talking about ... so anyway sorry we got off on the wrong foot and your 2 cents was no help but I thank you for it .. so thanks ...

 

Alright U4Gn, sorry about that.
It just bothers me seeing the "blanket terms" thrown around, I don't like it being passed down more generations. It's very useless knowledge. When I ask a car guy what he's got in it, and he tells me "202 heads, 3/4 race cam, etc" it just makes me want to rip his arm off and start beating him with it. Those terms have virtually no meaning.

You can find all the casting numbers you need there, which heads left GM with 2.02" valves in it from the factory.
What I was trying to convey was that you really *really* shouldn't get caught up in the valve size being your deciding factor for your heads. That's a mindset from back in the day. Many heads can create more power with smaller valves (as Five7 eluded to up there with the Vortec suggestion).

 

ok here is a link to mortec http://www.mortec.com/castnum.htm find some heads that meet your "needs" copy the casting number and go visit the junkyard, a decent chunk of trucks had 2.02 1.60 valves.... now since i feel that i have been somewhat helpful now i get to make a point....sonix was totally right....and most of those heads with 2.02 are crap and dont flow that good, vortecs will outflow them and they have smaller valves, valves are only half the equation, the runners are the other half and if the runners are more restrictive then the valves then it doesnt matter how big they are...and even if u are planning to port and polish them yourself they still wont do as good as vortecs i bet because the plain truth of the matter is if u had to ask what heads u needed then u wont be able to port them good enough, properly porting is an art its not just hogging them out as much as u can, cause here is the big thing flow is great but u need good velocity for a street motor witch i hope is what u are building cause if u are building a race motor with stock heads well ure gonna lose.....and i hope this doesnt come off wrong we are only trying to help.... Reason for editing: Dammit Sonix beat me to the link i took too long to type lol...o and here is my favorite "its got and RV cam" OK? gimmies some real specs *******...

 

Yea but I had been researching them and there was a bit of modifing to be done to get them to bolt on .. (if I didn't read someone post that just got the wrong set ) If I decide to go that route what vortec head would I look for for a 350 carbed . See I haven't meesed with the vortec's before but have on the fuelie heads alot so thats why I was leaning toward those

 

how much are u going to be spending on your heads?

 

Well its looking like 800-1000 dollars but I am hopeing that I can find something a bit cheaper . I am shooting for a street/strip car .. and I do know that the fuelie heads are (bolt on ) with no mod. so if I could find that in a vortec head I would be willing to give that a shot but like I said I really have no real exp. with these heads ..

i personally prefer the freedome series heads, aluminum is a plus, and valve and spring selection and a lil less expensive... should flow bout the same as the vortecs but with the traditional bolt style witch i think u want....cant beat the price...

 

thanks very much for the link i am liking the freedom heads .. and they are a direct bolt on thats even better . so thanks agian for the help ..Also someone was saying on this board that certain year vortecs would fit with no mod I think .. If so what years and car(truck) would I be able to find them on . so maybe I can get away with some junk yard heads and refurbish them .

 

062 or 906 casting number is vortecs. 1996 and later 350 chev trucks.
You will need a vortec intake manifold, those go hand in hand. Still though, should be able to get it all done for $500 or so.

 

would those patriot heads fit a 305 and help it breathe better than stock heads?


i got a bored .030 over 305 stock heads sealed power overhaul kit.

mild street/strip cam. holley street dominator intake . edelbrock 600cfm carb.

or will it be worse than the stock heads?

 

We'll try to overlook your thread highjack.

Factory 2.02/1.60" heads are completely inappropriate for a 305. They will have large chambers, and the valve edges are so close to the cylinder wall that they don't provide any benefit over 1.94"/1.60" valves. Most of them are also the crappy 882 castings, which aren't good for anything but keeping things from moving (like doors and boats).

The 305 heads are 58cc chambers. Vortecs are 64cc. The 350 Vettes with aluminum heads had 58cc chambers vs. 64cc for iron to raise compression to make up for the heat loss through the aluminum material.

Now, what heads would be better than what you have? On a 305, next to none. The main reason for that is your stock 305 heads are pretty darn good, even on a 350. But, on a 305, the Vortecs would come closest, and would be even better if you had them shaved to 58cc. The sdparts link is a really bang-up deal, since it includes the intake, gaskets, bolts, and rocker arms that you're going to need anyway.

The next best choice would be to take your heads off, have the intake seats machined for 1.94" intake valves (and the exhaust for 1.60" exhaust if you like, but the rest you're talking about doesn't warrant the expense), and have the ports cleaned up and smoothed. New valve springs as well.

The Patriots are way wrong for a 305.

The Edelbrock carb is another bad choice. Keep your q-jet; get better gas mileage and go faster.

 

If someone said that here, they had better have been cyberslapped.

As Sonix said, '96-up trucks with Gen I 350, 062 or 906 castings. There are no other Gen I "Vortec" 350 heads (there are also 305 Vortec heads, different castings). '87-'95 heads are often passed off as "Vortec" because, the seller tries to say, they have centerbolt valve covers - complete bunk. There is no such thing as a Vortec head that will fit with no mods. (For the record, the factory continued calling their truck engines "Vortec" into the LSx years - those heads are completely different from Gen I heads.)

There are Vortec-style heads out there that have been drilled to accept pre-Vortec intake manifolds. Avoid the siren call - a pre-Vortec intake manifold will not match up to the Vortec ports properly, even if it bolts on. Use a Vortec intake. Complete silliness to even offer this dual bolt pattern "service".

 

hey blackmagic, I know where you are coming from. My dad and all his buddies grew up racing so I grew up around alot of it. Im very used to hearing heads called fuelie or 202s and 3/4 cams and such. But times have changed. The reason they could do it was because at the time, there was nothing else. Today 202s could mean several different heads. Its best to start calling them by the last 3 digits on the code. For example "fuelie" heads that had accessory holes are 186's and those that didnt are 416's. as Im sure you know they came in different valve sizes with 202s being the best.

I looked into the same thing you are doing. I wanted to build a very good street/strip motor for my s10. I originally bought a set of 186s (fuelie, camel hump, etc) heads with intentions of rebuilding them. But after I figured up the cost of valves, springs, and a rebuild, I was looking at just under a grand. Truthfully, unless they are professionally ported and polished, a stock vortec head will run better than the fuelies.

I didnt want to swap intakes and such so I kept with the older design and bought a set of Dart Pro1 Platinums for $1100. I couldnt have been any happier with my decision.

 

i apologize for the thread hijack.
wont happen again.

just seemed ok to do since the origniators topic was covered.
but thanks for the help.

i guess if i wanted extra performance i need to build a 350..

nothing wrong with the 305. just want more performance.

the car MOVES!!

taking out most 350 camaros and motecarlo's

even 302 and 4.6 mustangs. but i want to go more into it.
thanks for the help

five7kid
you are absolutely the best at explenations.

now i threw out my qjet.
but would the qjet work properly if it didnt have any of the sensors hooked up?
i cleaned up the engine bay by cutting every single wire i didnt need.
so all i have is the generator wires, distributor wires. and a few others.

 

A stock U.S. 3rd gen q-jet wouldn't work properly. A non-CC q-jet would be fine.
