This is not a chamber where I would sink valves to add volume.
Just curious,why???
Would you install a 2.15" intake valve?
Thats how you get the big flow #'s out of the "lump" heads we did....330 CFM+, I think I remembered you asking Twisted6 a while back what he thought was being done wrong or different with the #'s you were seeing with the bolt-in "lumps" in comparison, thats the difference, plus a lot bigger port. Needing to feed a 10,000+ RPM, super high compression race engine requires a little more extreme measures that an average street/strip engine....You wouldn't believe how much valve lift we were running if I told you either....
