you would need something like the 557 m/p cam with 10 degrees more duration than the small 528 241vs251 dur@50.,will blow off some more static comp dynamically.msd box for sure puts in 3 sparks instead of 1 up to 3,000 rpm the ping city zone 0-3k,the right fuel mixture cant have fat girl rich carbs, piston design plays in as well less sharp edges the better,for not holding heat,ceramic coat tops of them for sure.when testing pump gas comp limit, 915 head is the way to go for sure,closed chamber wedge heads have perfect quench area and cause blow down/cross turbilence to cool the head piston area on every tdc fire. if piston flat has proper quench. thats why proper quench can make a 10.4 comp motor run like 9.4 on 93 octane. a .060 in the hole motor can ping on 93 @ 9.4. follow these steps and you can make it work for sure
