Have some questions regarding SBC Gen 1 parts compatibility. The short block is a 1988 350CID (5.7L) non-corvette with factory roller cam and center bolt valve covers; one piece main seal. The block ID number verifies it is a 350CID, cast between 1987-1995. Unfortunately the VIN tag on the head deck has been shaved off probably from decking the block. Apparently during these years, 350 engines for Corvette and maybe some model Camaro is completely different? Heads and intake from a 1988 Corvette engine will not work on the block I have because of the reverse water flow design. Also will earlier SBC model heads made for the 2 piece rear main style SBC block fit on this 1988 block?
