Default Flow #s of ported 317 heads(not mine)

These are some flow numbers of a set of 317 6.0 heads that a bud has that wanted me to check out and so I sent em off the be flowed to see were they are as they sit. These heads look to be nicely done(by a well known LS1 shop) and I thought I would post up the #s since I had seen alot of flow #s posted lately. The port volumes are 232cc intake and 84cc exhaust and valve size is 2.08/1.60. The exhaust was flowed with a pipe:
3.900 fixture
.200 133/111
.300 196/147
.400 251/174
.500 282/196
.600 293/214

4.125 fixture
.200 136/113
.300 199/150
.400 257/180
.500 294/208
.600 313/230

The intake gets turbulent at .550 and higher on the 3.900 fixture IMO mainly because of the 2.08 valve. Just a little info for ya.

That's about average. Nothing spectacular but the mid lift are good.

I am not at liberty to say, do not want to get into all that. I feel these are probably average #s that most people will get getting on this type of cylinder head of this size.

Understandable. I didn't think you'd give out the name anyhow. Those numbers are pretty good for a random set of heads from a given shop. Nothing I'd pay 2k for tho.

what type of radius plate was used? .200 - .400 lifts look low on both bores despite the 2.08 intake valve.

They were shrouded in the 3.900 fixture and are about average for the size port in Tonys head flow thread.
