Hey guys! I recently bought a mill and was thinking about milling my predator 420's head down a few thousand along with a thinner head gasket. Any thoughts on this? Comments, concerns, and tips welcome! I just would like any helpful info on what I might be getting myself into before I start milling the head down or doing some extreme porting. I'd like info such as: pros/cons, or generally helpful tips. Thanks!
