Ramm,
Because I honestly do not know, can you explain what the affect on the same engine would be when comparing the .100" cfm numbers as cast (69.5) versus the ported number of 91.5?
Note: I have swapped from 2.02" J heads to these ported SW's and I assume the flow of the J's are a bit lower at the .100" lift. smile

I am wanting to understand your "cammy" response because I am now driving around on these heads (with same cam/rocker setup [listed in sig]) and I am noticing some differences.

Thanks!
