318 LA hp and torque question

Rumblefish 360........I have heard that 318 application 302 heads with 2.02/1.6 valves and ported fully will only gain roughly 30 cfm on the intake port which puts them roughly equal to a set of same era un-ported 360 heads, flowing roughly 215 CFM on the intake port. Does that sound about right to you? Sorry to hi-jack but there seems to be a bit of controversy on what this head will flow.
