Yep....... went back and looked at my combo. Ran 10.74@ 124.60 best. Typically in the 80’s.
Having a 904, bigger tubes on the headers, or full out porting( somewhere close to 290@600) on the heads would have made it run a bunch better.
An Eddie is actually a pretty darn small head for a 4 inch arm, but with care you can run 125mph at the weight you are with attention to details, without a roller and with modest compression I would probably make the heads as good as you can as a first option. I probably left thirty horse on the table with my combo just having them stage 2 ported by Hensley at the time compared to a full port by someone like Modern Cylinder who gets bigger numbers that make more power
