D2OE Intake/Exhaust flows?
Does anyone out there have the bench flows for D2OE heads (429 PI) ? Stock versus say stage 1 ported? I got my hands on a pair of these heads and I want to get some idea (using Desktop Dyno) of what direction to go with a 460 buildup using them. I am shooting for 450-500hp with pump gas and a still usable truck low end torque curve. Any help would be appreciated.

I had a set of PI's with 2.24 Intakes and 1.72 Exhaust plus at least Stage 1 porting( don't know all that was done but lots of time spent). They flowed Intake-266,297,309,309 and Exhaust-158,181,185,193 @ .400,.500,.600,.700. Good heads for cast iron. I then went to Edelbrock Perf RPM which flow I-274,313,328,332 and E-185,216,232,247 with mild porting. FYI

Thanks Wallly 460
That gives me some numbers to crunch. My plan is to remove the thermactor hump on the exhaust ports and just do a mild clean up on the intakes and the numbers you got look fairly close to what I am expecting.
