I have a set of heads that came off of a Mercruiser 800SC. the block is a 572 tall deck which I heard is a 427 tall deck block, I know the is a casting in the heads that say HI-Performance GM with 2.20/1.90 valves. I will look later for the numbers

The only cast numbers that might be of some info that I found are (14096188) if that will help or maybe somebody can run the numbers to see if they would work. They have about 102 Hrs. on them. I lost a rod on one engine (not the one that the heads came off) so I decided to rebuild both and go bigger (1100's) :cool:
