I've got two questions about these heads.
First, are all FE head exhaust ports this....bad? Or was it just on these first few years of heads? The port is nice an large, but there is a big step up on the exit hole. Almost like the exit hole was an after thought.
Secondly, given these chambers are ~60cc, would it be possible to run these on a z-code 9:1 '62 390 engine? The cc would decrease by around 14cc, which I'm not sure would be too much or not.
