It is a suprise that the intake worked at all. The head on the Pontiac is about 1 inch longer. It does share bore spacing and size, plus you can put a crank from a 292 in it, but most other parts are OHC specific. The complete gasket set for a Chevy 250 will cost you about $35.00 but a set for an OHC will cost adout $115.00 ( 6 years ago) and it will probably have to be ordered.
