Double check with some of the online sources, but I think the cyl heads

Which would mean the intake and exhaust ports & gaskets are the same?

ok - that's what i needed. believe me, i have been to napa, and
several other auto parts local places. plus talked to marineparts.com
and go2marine.com - no luck. knowing that they interchange gets
me on track - in fact i might even be able to find those 77+ gaskets
in stock locally today. thanks!
