What is the highest FLAT TOP piston compression using the Secret Cams/L.O. Cams with a .054 stock head gasket or a .030 head gasket before you would have contact with the valve? Installing oversized valves and port matching head what piston bore oversize would benefit the oversized valves and port match? Using super pump fuel. Injector size upgrade? Wanting for a 10.5-1 CR and will try dished pistons if only avaible for higher cr.

Why dont you mock it all up with the pistons you have and with clay and measure the clearance you have with the stock pistons? Then order the pistons you can fit.

I did the clay trick with h.o. Cams and had good clearance...so im sure u will be fine with the l.o. Cams
GMR has got nothing on this
honestly.. ive yet to see anybody have piston to valve clearance issues with all kinds of set-ups around here.
Wonder what my problem was. I wasnt happy. Do you still have my old flat top pistons?
Lol man that pissed me off so much. I still wish that had never happend. When your 500 miles from home valvesand you hear your motor valves going through the pistons its a scary sound.
Wait wat happened to your build?

That was his first build a Looong time ago.
were thinking it was valve float do to spring failure. but then again it was almost 7k rpms using manta stiffend sports springs on a cam that has 416 lift and 219 dur. intake valves hit the pistons one went almost clean through, destroyed my head block and one rod. i never saw that engines full potential. i was very disapointed when that happend
