TPIS Corvette aluminum cylinder heads. The casting number on these heads are 10088113. These are not LT1 reverse flow heads. These are 1988 through 1992 D port aluminum heads which take the standard 1955 up intake manifold. I aquired these heads from a badly wrecked 1990 corvette that a friend of mine parted out, Everything on the engine was TPIS from Mini Ram to oil pan. I am assuming these heads were ported by TPIS also. I completely rebuilt these heads for a project of mine but i have since sold the car and have no use for these. The work done to these heads are as follows:

1. Heads were glass beaded and pressure tested. (No leaks or crack repair)

2. 16 new bronze valve guide inserts installed.

3. Three angle valve job preformed in Serdi 100.

4. Heads were resurfaced in CBN high speed milling machine. (I had these heads installed on an engine but they were not ran, the head gasket left some material on the surface so I cleaned the surfaces with a bristle disk. If the winning bidder would like i will resurface the heads to give them a fresh finish)

5. Brand new K-motion valve springs were installed part number K-700, good to .525 lift. Retainers are used cromoly.

6. Valves are used manley stainless steel 2.00 Intake and 1.56 exhaust

7. Heads have 5/16 raised guideplates and 3/8 screw in studs. If the winning bidder would like i will upgrade the heads to 7/16 studs for an additional $20.00.


What's a good price for them?

Yes they are good heads! But you stated in your thread they are from 1955 and up Manifold, that statement would not be correct, The heads will not fit just any Manifold from 1955 and up!

I believe, and someone correct me if I am wrong, that you can only use a manifold on these heads from 1987 and up on the L-98!

Most Manifolds are from 1955 thru 1986E(Early heads).

Now as for the price for those heads you could do a search at various performance shops to find out a price that is comparable to what you have spent or if you want to move them you can adjust your price! It is up to you they are your heads and they sound good and desireable!

As a matter of fact, let me know how much you would like for them! Please PM me and let me know your asking price!

Thanks, Matt

Would my 89 alum heads ported and polished flow better than these?

The heads you're talking about are the same as the heads on your '89 (the casting numbers are the same), so whether you buy these heads or get yours ported and polished, you end up with the same thing.

If you can get your heads ported and polished (with the same upgrads as these heads have) for less money than you can buy the heads your talking about - and, of course, you don't mind the downtime - then go ahead and get yours ported and polished. Otherwise, buy the ones you're looking at.

They are on Ebay if you want them. Listed as TPIS Chevy heads. I'm not gonna get them so go for it.
