Flow Numbers

[bignbad60]

Any of you guys have any flow numbers for 333 heads with 209/172 valves ? Thanks Tim

if you don't have #'s for the 333 how about 580's, I assume they would be fairly similiar...Any thoughts?

Big,here's some flow rate #'s I got out of the Show Cars catalog.

1962-1965 Truck..3819333-flow rate 180 C.F.M. with 2.19/1.72 valves 230 C.F.M.

I wonder how the 690/583 head flow rates compared to later big block GM or those produced by the early Hemi's ..... or F**d. Some unproven local "discussions" as to, that they were very similar.
