New motor.....

After you mentioned the intake gasket I started thinking, the block is a 76 360, the heads are 86 318s that have been reworked with a full port and big valves, and the gaskets are the ones that came with the summit rebuild kit for a 360 (got the heads after I started the rebuild) so maybe the gaskets are blocking off a water passage??? Is there a set of head gaskets that will work better for my combo or am I screwed?
