OH one last thing that I forgot, in an article I read on supramania I think, they talk about NOT port matching the exhaust ports to the exhaust manifold. Apparently it causes a lose of low end torque. Heres the exact 'quote' from the article:
"Opening up the exhaust ports on the head removes the reversion dam and will cause you to lose torque because the manifold will no longer scavenge the head"
Thoughts? I thought that the pulses would occure BETTER with out the intrustion rather then with?
