Well, Welcome back race fans, it's time to teach Lindy something again.

I have a set of closed chambered heads. I believe 516's. Larger valves have been installed and the bowls look to have been more than cleaned up and polished. I was thinking about taking them to a shop to have them measure the volume. Prostock1320 and I were discussing them and possibly having the volume checked. What's your take on closed chamber heads? Junk or good?
