And not to mention the much higher chances of pre ignition from all the sharp edges of those 8 valve notches along with the added collection of fall out fuel in those 8 notches .
This fuel either burns too late to make power because it burns in the exh port making for added engine heat, or if it does light off does so in the form once again of engine distroying detonation.
I am of the opinion that Those 8 notch pistons from day one have caused more issues then they solved on average!
Pistons with a overly large dish which worked for both early and late heads which dropped compression a tad more then those 8 notch pistons would have made more power without the bad side effects.
