Are different heads, or trying to improve the high-lift flow of the current heads, an option? Otherwise, it sure seems like you're jumping through some hoops to crutch those heads with an oddball cam. Doesn't look cost effective to me.
No...not really.
the pistons are for these open chamber heads..closed chamber wont work with these pistions (hense new motor on stand)
the rocker gear is specific for these heads..(offset intake rocker and the spacing and clearance are all set up.)
the cheapest way to keep this motor is new roller springs and a new cam...fwiw
i am afraid to do more porting on the heads as i would hate to go backwards..fwiw.
but if i could find a simple solution to getting the .500" flow numbers from falling off. id consider this.
