Missed on this combo?
Well drove a couple hours today to Tom Hemphill Racing to get the heads checked out.
He was pretty anxious to check em out. Mostly works big block or W9 and W2 stuff. Boy were we both surprised. I took a pic of the numbers rather than all that typing.
What I liked was he said cfm doesn't always tell the tale but he said they SOUNDED great. Lot of noise to me but he said you flow enough heads and you can hear how they'll run. He flowed them like everyone, I guess.....28 inches...
He did say Hughes must use a pipe on the exhaust side. That would account for the bigger numbers there. For some reason he doesn't use one.
He measured all the ports with some inside caliper thing and said they are all very uniform. I guess if they're set up right, they all should be damn near identical.
Overall he gave them a thumbs up. He seemed pretty happy with em. Velocity a bit high but not too bad.
Checked out my cam card and dyno sheets ....like all of us he says something ain't right. Heads should support a good bit more power.
So they're not quite what they advertised, but awful close. Maybe I got lucky.
