need suggestion about putting 13:1 c/r on my gsr. is there going to beenough piston-valve clearance? need a thicker head gasket? by how much? and later on the road i might plan on getting skunk2 stage 3 camshaft, is there going to be enough piston-valve clearance also?

 

that isnt gonna be very pump gas friendly
