Critique my planned combo
Your piston to head is too tight. My machinst and friend builds badass World of Outlaw motors and him and I have had this conversation and there is no reason to run the piston any tighter than .040. He has hundreds of dyno hours logged and there is no power made when having the quench tighter than .040 with a steel rod.I would also run a cometic head gasket just because 10 head bolts suck and the cometic will give you the best seal without worring about them blowing out. At .031 piston to head it is very likely that the piston will hit the head.
