Proof of hours? Built by who? Dyno sheets?

Good catch. Now see if you can read the numbers on the exhaust side. I thought I would be able to tell what kind they were by exhaust port but I can't.

The side of head string looks like it starts with PC. Could these be pro comp heads?

X2. Also OP would be very helpful if you posted a little more about the engine and history. I realize you trusted brad at performance boat center however the words like (roller, billet, forged, CNC, H beam, etc are pretty much meaningless. Example if brad (seller) told you the heads are "C&C" he should certainly know the manufacturer. Or maybe not considering C&C. I'd suggest doing a little investigating and identify exactly what you have the best you can. You selling this for new build? If so what were your speeds and rpm on the water were you getting. There's got to be a build sheet or builders name somewhere. Don't get me wrong the engine looks great but it smells a tad bit like "perfume on a pig".

Identify some parts. Did you do a compression test and or leakdown?
