There is a guy selling his L98 vette heads, freshly rebuilt for
$6-700. Is that too much? Here is some info:

Jet washed
Sandblasted
Chemically magnafluxed with penetrant dye
pressure tested
Resurfaced
3 angle valve job
New 1.5/1.94 valves
New springs(110lbs, .525 lift)
New 3/8 screw in studs
New raised guide plates
New positive valve seals
New hardened valve locks

fresh rebuilt pair of 1989-93 L98 Aluminum Corvette #10088113 cylinder heads. They are 58cc and would work great to put on your special project out in the garage. All of the intake manifold bolts on these heads are at a 90 degree angle....meaning these will also fit the older style (1955-1986) SBC engines without modifications. You would just have to use a centerbolt style valve cover. The valve guides in these heads were not replaced as they were in excellent condition. I have seen these heads go for as much as $4-500 for an unrebuilt set. GM wants $500 each for new ones. They also offer a 50lb weight savings over cast iron heads.

They look pretty good. You guys know anything that would help? I'm on a budget, but also won't have a car until I finish building an engine. The last major part I need is the heads.

If these are too expensive for what they are, know any good sources for buying a good set of L98 aluminum heads?

yea, your getting ripped hard, you can get a good set of aftermarket aluminum heads that flow numbers those heads could never dream of. Look at a set of GM fastburn heads, or world products sportsman II's, or even might get lucky and find a set of darts or afr's on ebay for $800, i don't care what anyone says, L98 heads flow like ****...

possibly a pair of complete heads for around $400?

I'm sure you can get a fully prepped set of Vortecs from Scoggins Dickey for less than that--and the Vortecs will be much superior flow-wise.

The ONLY way to really save money is by following the advice linked at the end of my sig. You won't regret it

That's the problem with working up stock heads...

That's a fair price, based on the work that's been done; but like they said, you can get better heads for less some other way.

You sometimes have to wonder about these vette heads, is there more to them than just flow #s. With the flow #s I have seen I wonder how it is ever possible that they make 345 HP on a ZZ4 motor. Is the angle plug design a huge benefit that we overlook?
Anyone else curious, or have any answers?

RB83L69

The ZZ4 doesn't have TPI on it, it has some kind of real almost performance-based induction instead. That's why it's capable of producing so much more HP than the otherwise very similar L98. Plus, the spec is without any emissions compromises at all.

Six bills is a fair price. For all intents and purposes they are all new. Only thing is that the raised guide plates won't clear the inside of a stock center bolt valve cover.

I'd also tear them down to double check everything and port them a little (clean-up and pocket).

Ya I saw those on ebay too.....They are real pretty,but overpriced.........SDPC sells them for like $420 a piece....

Proximo

Where?


I want to do that more than anything...2 problems. The only set of fully prepped original heads I found cost $700 from ebay...its over now though. Second problem...I don't have the time to work on it much less wait for it to be finished. I barely will have time to build the thing in my spare time.

Yes, if you don't have the time then you NEED to have the money

But drop F-Bird'88 a line and see if he has a set already done and ready for sale. He is our "hero" in this endeavour and does sell a set now and then, and for a VERY good price--usually around $400 US

How about the Pro Topline Vortecs, they are a much improved version on the GM Vortecs for less then $500 assembled and blueprinted.

I think they are on page 5, because they are in the paper catalog.

I can save the money..just looking for the best heads (this means PAIR..not the price of a single duh) for $800 or less hopefully. The magazine article used vette Aluminum L98 heads ported and polished. But it seems that those in stock condition are more expensive than Vortecs!! At least at SDPC.

*sigh* Actually, I just need to get the cheapest heads that will deliver some power for now...nothing fancy. I just need a car that runs. I have a pre-87 (I am pretty sure) TPI setup, and a '73 vette 350 block being rebuilt. I just need heads to get it going(plus the nickel and diming to death in between).

ARGH, even as I write this I am being torn between buying the cheapest heads now and having a running car, and saving up for the best heads for my application. The article used L98 heads, so the best bet is to go ahead and get the closest to those as possible so I don't have to come back later and buy more stuff. I can just port and polish them when I get the chance.

Most of these heads I see are pretty expensive, so it'll be a couple weeks before I buy one so I can keep considering until then. And I think I'll contact F-Bird'88 and see what he says. Thanks guys for the help!

Hey, would 64cc fast burn heads work ok for now?
