Okay i am sure i have a 302 block (after checking the ford engine data on here) what i am not sure of is the heads. The heads have 351 stamped on them. This is a motor out a mid 70's ski boat. Mercruiser 188 hp. That i believe has been rebuilt at least once. Any help?

Welcome to FTE.
IIRC, the casting numbers for those heads are under the valve covers like so:

351W heads on a 302 or even 289 was a performance trick in the '70s. It gave you bigger valves and ports at the expense of a little compression due to the larger combustion chambers.

Actually, (and I might be incorrect to a degree) Ford Marine engines usually had the 351W firing order, which means a 351W cam.
I believe they also used 351W heads.
Not a "mutt" - just the way it came from Ford Marine.

Might have been a 302HO.
In the case of the 302 HO, same thing, I think. 351W firing order, roller cam, and maybe even 351W heads. I didn't get involved in the 302HO much back in the day, so I can't be sure.
