Agree with that... 9.15- 9.5 deck better suited as it allows much lighter recip pieces. Smaller mains mat not be mandatory but would help. I think lifter bore angles/ positioning and rocker position have to compliment each other. Multiple angle pushrod travel aint going to cut it. Pushrods could end up longer than you'd think with a short deck but not likely as long as a 10.2 deck... IMO rocker fulcrum point raised would help decrease angles seen thru the arc as would a lifter bore angle that compliments the valve/rocker layout.

As far as heads... I cant disagree that there are a few we already have that are candidates to top this motor.
