these are junk stock smog heads. Go to a local junkyard and you'll be tripping over these left right and center. I wouldn't pay money for them, so I didn't even notice the price.

Air_Adam

Junk... Sofakingdom actually pays people to TAKE those heads away from him!

camarodrew

thanks do yall have some good head numbers so i know what to get and what to stay away from

how much are you planning on spending, and what do you want to get out of the car?

Air_Adam

If you want reasonably good factory castings, look for 416, 601, 081 or 083. Do a search on these numbers and you'll find piles of info on them.

camarodrew

what do yall think of 193s and um not to much money

Sonix

iTrader: (1)

That's what are on your block right now eh? Well, you know what they're like, you're running them... fast enough for ya? no? So then, you have your answer.
answer this question in more than one sentence, and you'll get some good advice.

Air_Adam

Better than 882/993, but still a casting to avoid. They are the fabled 'swirl-port' heads. Good for trucks, bad for performance engines.

camarodrew

well the motors gone and im just now 16 and dont have my real license yet so when whith my granddady i dont drive to fast and i dont know how much i could come up with if yall could give me some numbers that would help

thanks

Since this thread is a new topic, I'll ask the same question. This car is somewhat of a daily driver. I don't drive it on schedule but I drive it fairly often. I was wondering about two styles.

What would be a good set for a street machine to push it to 300-350 RWHP

Also, what would a good set be for total ***** out power, up around 500 RWHP (naturally aspirated) using a 350 engine (of course not the stock one).

drew - you've got some growing to do, and some $ to earn. Leave it stock if you're just learning to drive on it, and can't drive it fast due to the elderly in the car... (what the hell is "grandpa" doing in a camaro anyway??)

douchermann - you've kinda got a different question altogether, suited to a new thread. Heads to get 380HP lets say, you'd be looking at vortecs, or aftermarket. Not a lot of factory castings will do that without making it completely unstreetable, and/or having it ported like crazy, and REALLY knowing what you're doing. Some basic 180cc intake port heads in the aftermarket would do it. Canfield, Edelbrock, Trickflow, etc.

500RWHP is a beast. That's like 600-650HP at the crank. In a 350, that's a ***** to the wall racing motor. Like a 220cc intake port set of CNC ported AFR's and a 250/260ish .700"+ lift solid roller cam. Absolutely useless street driven. Again, aside from the few "exceptions" online here, who have a different definition of streetable, and know some tricks to making it "behave".

Air_Adam

300-350 RWHP is about 425-500wfhp. You won't get that from any junkyard castings, you need to visit the aftermarket. 195, 200, 210cc heads like those from GMPP, AFR, TrickFlow, Dart... you'll need heads like that to make those kind of numbers.

500RWHP? I'd say use something no smaller than 220cc, then use a turbo/supercharger/nitrous. Thats REALLY close to 700fwhp, which is asking alot from a 350" engine. Thats 2hp/ci.

Alright thanks, thats all I wanted to know.

Air_Adam

If you want a stout 350 that'll beat up on the other cars at school, and you are building it from a naked block (?) then I'd highly suggest a set of 416 or 601 castings. They are 305 heads from the '80s, but they are junkyard GOLD! They are built quite beefy compared to 624/882 heads, and they have a really good chamber design. Nothing compared to modern aftermarket stuff, but its a better design than the old double hump heads, which are still popular today.

I have a set of 601 castings on my 350. I had bigger intake valves installed (1.94/1.50 valve sizes... 1.84/1.50 is stock) and screw-in studs and guideplate machinework done as well. I'm quite impressed with these heads. They are a HUGE improvement over the 882/624 heads I had before... I had one of each, lol... the gas mileage stayed about the same, although it needs premium fuel now, since my 350 has flat-top pistons, but the power gain was incredible.

I think Sonix could back be on this, as he built much the same engine that I did, although he used 416 castings.

I have had the same engine as Air Adam. 355 with ported 601 castings on it. I ran it with a cam that spec'd 204/214 @ .050, .423/.446" lift. I then bumped it to the LT1 roller cam, with the LT1 cam it was probably close to 300 RWHP based on the track times in a 5,300 lbs beast.

Cleaned stock castings with low mileage (guides in great shape)


Various stages of completion










FWIW, I pulled the stock pressed in rocker arm studs out, tapped the holes, and installed the thread in studs and guides in my garage. The port work was done in my garage. I did however send ou the heads to have the valve seats cut for 1.94/1.60" valves. These heads were actually put onto a 305, before the 355, but they ran equally well on both engines.

Lift Intake Exhaust
.050 35.60 15.00
.100 72.40 47.00
.150 105.8 72.50
.200 133.4 98.00
.250 154.1 117.5
.300 180.6 137.0
.350 195.5 145.0
.400 209.3 153.0
.450 217.4 155.0
.500 224.3 157.0

i just want to have a little fun at the strip and just needed some heads to get me out of the 180 hp range and i drove my car for the first time by my self and it was ungodly slow i dont like saying this but ive rode in geos faster than my camaro

camarodrew

and 355 how fast are you running

Sonix

iTrader: (1)

tune 'er up!
even with heinously bad parts, a 350 in a camaro WILL make you sit up and pay attention. 'specially if you're not accustomed to driving 400HP beasts (like some people are, who will tell you that your combo is slow.. if you're used to a geo, a 350 camaro with CRAPPY parts, WILL be fast).
It needs some tuning done up hardcore. Start there, it's cheaper

They went a best of 14.7 @ 92 with the 355 in a 5,300 lbs fullsize van. Mid-low 13s or better in a F-body.

With the 305, XE-274 cam, Edelbrock Performer RPM intake, Edelbrock 1406 carb, 1 3/4 x 3.5" headers, and dual 2 1/2" exhaust with X-pipe it went 14.9 @ 95 in the same 5,300 lbs van.

iTrader: (2)

Huh, did you machine the tops of the stud bosses before bolting the guides down, or did you just leave them as cast? I’m guessing you drilled out the pushrod holes also?

dmerc

Hey Adam, Are those heads the same as the stock heads on my 83 trans am with crossfire injection? I know they are the high compression heads. Have to travel 60 miles to get the casting numbers so I was wondering if you know.

Air_Adam

If it has the original engine, its got 416 castings. They are basically the same as the 601s, but the 601s have a little bit better chamber design.

dmerc

Thanks for the reply. Ok, which is better the 416 or the large chamber 441 heads that are on a 350 I have. Which head would be best suited for use on the 350?

Sonix

iTrader: (1)

Why don't you start your own thread? You're not really on topic of the original thread...

Air_Adam

416 and 601 heads are very similar to the vintage double hump heads, only with smaller chambers and smaller valves. Install bigger valves, and they are better than the double humps.

dmerc

Yeah, your right but the original question was about heads and I thought since you guys were answering his question it wouldn't hurt to ask about mine. Didn't mean to step on any toes.

Air_Adam

Its no big deal, just a suggestion for future posts
