Does anyone have flow bench numbers for these heads?

I'm not looking for the MFG data, I'm wondering if anyone has a set which
have been tested out of the box without valve/head work.

I want to compare the MFG specs against other bench tests to select a new
camshaft.

I'm currently using Comp Cam 292H with 1.5 rockers.

The engine would be a 355 Chev.

Thanks.

Lift Int Exh
050 40 28
100 68 57
200 132 102
300 187 131
400 225 150
500 240 164

So says Chevy High Performnce's flowbench. Seems believable to me. I've looked at these heads disassembled on a bench. The intake looks decent for an as-cast piece. The exhaust looks as bad as the flow numbers indicate- almost like a stock production exhaust port.

Thanks Damon,

Seems like I'll need a little more lift and duration at 0.500".

The current valve lifts to 0.501" (everything being perfect). That's not
at good screnario at all.
