crazy4acutlass

Ok i have a 1967 olds 98 with a 425.I have a few questions. Will a HEI fit without any mods to it. I read in a mondello book i have to have the canm gear shaved. Anyone else? Or what to look for? Part two. The motor runs great and it has C heads with holes in the side for a smog pump? According to another book they cam on Cal. Cars or W 30 motors. This car is from Mi according to vin. Anything else i need to know or can do cheap for performance before i use it in a Cutlass? Should I use a Edelbrock performer intake on it? Will the manifolds and brackets be ok in a Cutlass?
Thanks Greg
