David,
You might check what version of the RFD / Victor head that was, ..
we / I build 4 different versions at this point, ..
It's likely it was a 2.35" valve version as the 2.4" version has been confirmed by several engine shops to flow as well as the -3 at high lift and out flow it in mid lift. But we know peak flow numbers aren't everything.
Comparable engine builds by several builders show the RFD to make slightly more power and better average power.
These are on typical bracket builds, .. not builds with 200+ dyno pulls
and fully ported intakes max effort stuff. I build a different head for that.
I have a new version for 598 - 632" that is going to surprise everyone, ..
back to the original post, .. I think if you're running in a class where everyone
is using a big chief style spread port head, .. you have to do the same.
Even though I build conventional heads that can make 1200 on
high end builds, .. the big chief will still make more power
when the same effort and money is spent.
now reduce the "effort" of the build to something the average guy can do,
and it'll be easier to make 1200+ with the big chief.
