[X72GPX]

Have a 400 30 over, eagle stroker crank, h beam rods, torker II, with iron heads that need a rebuild, so thinking about tossing them. I have set of speed master 72cc heads I would like to use instead of the iron heads.

I ran this calc off butler’s site, assuming I use their copper .093 head gasket. Are my figures correct?

If so is 11.18 too high for pump gas, and would a 108 LSA cam help this deal be more pump gas friendly? (have not selected a cam yet)

Have a 3.36 rear and continental converter “should flash 2800-3200”.

Thanks all
