Need to find casting # for Prc heads There's a local race I want to run, that requires stock cast heads, but Prc filed the casting numbers off my heads and put there logo there. How do I prove they are gym cast heads, which they are?

Take the valve cover off and the # is inside in the middle. See in the pic 4243 is inside the head. That means it is a 243 head. On my 5.3 heads it has 1706 which are 706 heads.
