Thanks for the advice, I will check the riser and manifolds also, at minimum will put all new gaskets.

Thanks for your comments everyone. I am taking the heads to machine shop to be inspected and have any needed work done on them. I do not have a machinist straight edge but run a Long Carpenters square across block this evening and it seemed good, I will see about getting machinist straight...

To me, some did not break loose as easy as others. But still tight.

Another thought, the .060 bore could be causing more heat hence cylinder gasket problem

Good catch, I noticed as well, looks like someone had issue in past and just fixed the side that had trouble. I also found it is a Remanufactured short block and pistons are .060 over. It’s a 32 year old boat lot of things have been done over those years I may never know about.

Thanks, I have to have 10 posts on THT before I can post pics. I will do it there tomorrow. I really am not great at reading a used blown gasket. Even though there is no material missing. I am assuming those dark spots between cylinders is where compression is leaking.

I pulled the heads and here are the gaskets. I do not notice any missing material, but do notice some Dark areas between cylinders.

Yes, had each cylinder at TDC. I am getting ready to pull heads now, seems that's the best way to determine at this point.

I am having some crazy compression test readings and I was wondering what others may think this could be. I would think just something in the heads, but reading are crazy. I was expecting low compression on 1 or two cylinders but its the other way around, only getting normal compression reading...
