Stage I heads
The stage I heads came out of BMS in later 1978 or 1979. As I remember. Smokie did port developement to improve upon the earlier low port heads. He also worked on other Stage I pieces such as the block. I ran an IMSA Radial Sedan back then with help from Olds. and Buick. There were some pre production parts.
Can any one tell me about the later heads that are supposed to be similar? Thanks Den
