I’m running a 2.08 on my 4.030 bore so yes it would. I test on a 4.015 bore so I’m positive anything I port will work on a 4.030 bore. It’s the chamber that’s the biggest issue and the street, street strip guys are easy because most of those guys run a 1008 Felpro head gasket which has a 4.180 bore size. That gives me room to play with the chamber more.
