Depending on the piston dome....an extended tip plug is gonna hit

Never use them in a full dome BB OC headed engine

Most newer pistons have a notch for the plug but I still would not use extended tip plugs....

Thanks Guys. I’ll Try and find his build sheet. One of his friends had 45 deg of timing Shake head in it! We’ll see if we can get him a safe tune and make it live.
I Had no idea what plug it took and what most run. Our bbc TS motors have no dome.
