Piston Bowl Volume

[EPA Violator]

I need to know the piston bowl volume of the 04.5 piston and 03 piston please. I am thinking it's around 40 cc, but I need to be for sure to make things as accurate as possible.

Also, what is the internal diameter of the firering on a 12 valve head gasket?

Correct me if I am wrong but the spray angle of 03 sticks is 142 deg and 04.5 sticks is 124 deg?


Thanks,Jay
