how about this my set up built head including jun stage 3 cams supertech valves jun retainers and springs jun cam gears , type r bottom end and gsr tranny
right now around 11.5:1 comp. if i do ctr pistons comp. will jump to 13:1 correct me if im wrong whats the task if i go about doing this will crank or rods need to be changed no right just take the head off drop the pan and switch em out on a comp. calculator this is with 3ply gasket fyi ill have about a 6th for room or will valves hit the pistons

 

if you run ctr pistons with those cams and a 3 layer head gasket im pretty sure youll have to clay the motor....pct pistons arent the best choice in my opinion because of the dome and the flame travel it causes.

but I could be wrong!
