What casting # heads are good, I think I've seen 916, 882 and others on ebay.

Saw some Vette al heads goin for $500 right now, but prolly will go up.

 

Pull off a valve cover and check the casting # on your heads.
Then go to www.mortec.com and have a looky at the head casting # info list.

You'll find that your have large chamber 76cc smog heads.
Your motor has very low compression. all of the other large chamber (76cc) heads like 882's etc will not help you.

You'd best look for some 58 to 64 cc heads.

A set of Vortecs would really wake that motor up.
About your best bang for the buck.
Get a set and a matching manifold and do the required mod
and then bolt them on. You won't be dissapointed.

You would want to install them with a thin .015" "shim head gasket" to maximize your final cr with your non blueprinted dish piston motor. (exessive deck clearance)

 

I'd get those vor's but I just bought a stealth intake and don't want to shell out over $200 i think it is for the vor intake.

 

try looking in to some World Sportsman IIs...if you have the money they are GREAT heads...they will work with your intake...

they have 2.02 intake and 1.6 exhaust...and a little porting will make these bad boys flow...

My motor is at a performance shop right now getting built up...with the heads cam and intake and forged pistons ill be running around 400hp...

i was actually tryin to get some from a member of these boards that wrecked his car, though I'm not sure I can afford them.

 

ed's 1le?...haha...

Welp...they are GREAT heads...too bad that they are cast iron...you can get some bowties or some of the vette alum. heads from sdpc2000.com...

How much are you looking to spend?...you can always port and polish your heads that you have now get them flowing more...i have a set of 305 heads if you are interested in them...

I can't spend more than $500. So, I"m on a tight budget. I know of some that I can get for that brand new, just not sure of the brand, I have to find out. Ed's are cast iron huh?? that's ok, just means they will be cheaper so that I might be able to afford them.

My heads now are 76cc and I want to get around 10:1 compression.

 

the world heads bare (no valves and stuff) you can score them for around 300 bucks a side jegs

You should buy the heads bare so you can use the correct valvesprings ans stuff with your new cam...

they say the heads can add about 50-100 hp...right out of the box...i dont know if that is true...but they will increase your power a lot...whats the rpm range of your intake...is it a dual plane high rise??

I think you would be better off with the sportsman IIs...get the 64cc chambers and you should be where u want to be...ill be running a forged JE piston with the 64cc heads and ill have about a 10.3:1 compression ratio (my motor is being blueprinted and balanced and decked....

If you save up a couple hundred more you would be set...valves and stuff arnt that expensive...

I would try to stay away from the 1.94/1.5 intake heads...you will choke your 350....2.02/1.6 is a good all around street head....

If you have any questions please feel free to ask.... ive talked to u before on IM (DabeWhatRYaDoin)

Yeah, I want 2.02/1.6s. I already have comp springs to match my cam, but then valves will be $160 plus $50 for locks and retainers. So that would be $800 a little more than I want to spend. Guess, for now I'll wait and see what kind of heads the ones I'm lookin at are. I'm waiting for my brother to email me back about them.

 

Vortecs are the best bang for the buck even including the new intake manifold. You can't get good aftermarket heads for under a grand, and there's no stock head that comes close. The L98 d-port aluminum corvette heads are pretty good heads, and when ported properly can rival AFRs, but paying somebody with the talent to do them right (aka lingenfelter) will cost as much as AFRs anyway)

Get vortecs, get a new intake, and recoupe some of your money by selling your current intake on Ebay.

 

if i recall the vortecs dont have the 2.02 intake and 1.6 exhaust valves that he is looking for.....i looked in to the L98s....they would choke a 350....

DABE

 

Guess I'll wait to hear back from my bro about those other heads. But how bad could they really be, being brand new 2.02/1.6 64cc heads? for $500.

 

welp...u never know...let us know what brand and model they are...

Before you buy them...see if you can take them to a machineshop and have them check the heads for warpage...thats one thing you dont want...warped heads...even tho they are new they could be damaged in some way...also they are probally cast iron...the alum. are a lot more $...

LS1 heads don't have 2.02s either, but they will outflow every aftermarket small block head on the market. There's more to airflow than the size of the valves. The Vortecs are capable of providing adequate flow to support up to 400 hp. Then again, the D-port L98s are very capable heads too. They do just fine helping the ZZ4 make 350hp with a mild cam. They aren't the best head out there, but can be had cheaply if you know where to look, and aren't going to hold you back very much until you go past the 350-400hp mark. The Vortecs simply offer the benefit of being cheap everywhere you look. A lot of Corvette guys run the stock heads on 12 second cars. I've got one friend with a super rammed 350 with ported & polished L98 heads, LPE 219/219 cam that ran a 12.8 @ 108.66 with a horribly untuned 165k mile motor. He's got a friend with the same combo running deep into the 11s with the same setup (except his is tuned properly and he's got slicks/skinnies). The L98 heads can flow very well when cleaned up, and can approach AFR-level flow numbers when worked by Ligenfelter.

Hell... Lingenfelter used those heads on his 420 cubic inch motors.
