which heads are compatible?

[KQS]

Hi all!

I have a '89 Corvette with a '85 engine (cast iron heads). Is it possible to change the the heads to an aluminium one without changing the block itself? Does the L-98 or the LT-1 alu heads fit to this '85 block?

Not sure on the L-98 heads but the reverse cooling on the
LT1 makes that impossible. Your car is a gen 1 350 small
block, you should be able to find after market Alum. heads.

Have you looked into Trick Flow or Edelbrock?

Yes, you can do it. Youll need centerbolt valve covers and the heads. I believe the EGR setup is different on 85 too, as is the cold start injector (i think, i'm not sure).

I would get the 88-91 vette heads preferably, if youre not messing with serious mods. Theyre still good for 350hp untouched, so even with some major mods theyre great.

If youre going for a real engine down the road to make serious HP, id pick the AFR 190s. airflowresearch.com

LT1 heads will bolt to the block, but they are reverse-cooling and wont really work without extreme modification.

Thank you all for the valuable informations about the heads. I think i'll check the Trick Flow and Air Flow Resear ch sites for aftermarket head. Thanks to everybody again, this is a great and very helpful community!
