12554290 heads on a gen 1 SBC?
I am picking up a set of 12554290 heads from a 1994-96 LT1. Will I have any issues with these going on a gen 1 010 type block? Are these a good choice? I'm getting them dirt cheap. Is the reverse cooling thing an issue?

I did in fact there I found quite a bit about it on this site. I did search before posting this but must have did something wrong. Searched again and found all I needed and then some. 03-08-2013 09:16 PM

WILL NOT WORK thats why those heads are dirt cheap. Require a reverse flow block with extra water passages in front of block.

It can work but needs machining, vortecs are likely a better option or even better Chinese heAds and the of course better aftermarket heads.
