K-series or H-series flow numbers?

[integrawow]

What does the best flowing K-series cylinder head flow in factory (stock) trim? Or what about the best flowing H-series head?

The flow measurements should be at 28 inches of water, and the units should be in cfm.

stock h22 is close to 300cfm, i just saw one on a bench the other day with a good valve job that did 308cfm

K series should be about the same. Ive read somewhere(I think it was on K20A.org) the K-series are actually based off of the H-series; the K-series being a "semi-build" H-series that turns the other way.
