Been reading a new book by Pat Ganahl (a re-write around 1997). First I always thought it was a semi-hemi, but guess it was a true hemi. That kind of peaked my interest. I have a few questions.

Will a SOHC 427 fit it a Cobra or is the heads too big? By fit, I mean without massive changes. Slight to moderate changes would be reasonable.

Did any aftermarket companies produce similar heads?

Did anyone ever offer a gear drive or better timing chain design than the 6 foot rubber-band-chain that came on them?
