Gm 502 crate engine question(s).
just got in my 502 crate engine..IT IS NOT THE ZZ502..but the long block 502 with the cast iron heads.IE;TRUCK LONG BLOCK REPLACMENT.
question?...it says its a oval port head design but they look square to me,smaller than a normal square port but def not oval?
i have a oval port edelbrock intake i need to use for hight issues...what intake gasket can some one recomend...oval like the older 454s or the gen 6..200 and newer 454?
same quaestion concerning the exhaust gaskets...all the headers are round,but again these look to be small square?
any help appreciated.
gm engine part number...88890534 ht502
gm cyclinder heads it comes with.
- Cylinder Heads (P/N 12562917): Iron oval port; 118-cc chambers
