Pro Topline Specs?

[Rickracer]

I recently acquired a 3rd Gen Camaro with a pair of Pro Topline heads on the 350 block, the previous owner was no help with specs or receipts, as he bought it from somebody that was in jail. I'm planning a cam change and I'm trying to find out some of the specs on the heads so I have a good idea of the compression ratio. Both heads have the number 2234000020, one has 189401101T, and the other has 189431101T. Anybody know port volumes, valve sizes, or chamber sizes on these? Any other pertinent specs of info would be helpful as well. Thanks, Rick

That head would be a 220cc intake runner, straight plug, 64cc chamber head with 2.02int. and 1.60ext. valves.

FANTASTIC, just what I needed!!! Mucho Gracias, !!!
Does anybody have any "real" flow specs on them? That would be very handy as well.

Flow numbers are given on the RHS website for the 220cc heads.
