360 intake fit problem??

An MS90009 is the wrong gasket to be using on an aluminum head/ intake combo, and it was for a 318 port size too.

NAILED IT! Wrong gaskets. Port window to small for starters, metal thin gaskets for OEM 318/273 heads.

Edelbrock gaskets are .063 thick.
Fel-Pro 1213 are .0635/.0640 thick.
Metal OEM style 318 gaskets are .0150 thick.
Port window offset shown below.
