Mopar P4532900 head info needed

There's Magnum phone numbers all over the place I think the ones I flowed.. only flowed like 209 CFM @28"
The chambers are restrictive to low/mid lift flow. I have a set of 2/1.59 valve speed crapper mags for jimmer that do far better and they aren't even "worked" to that extent.

Thanks! Charlie never had a set on his bench. So he invited the heads to it. We’ll also bolt on a Chink AG and a carb to see what happens.

I’ll be using the OEM Magnum head on a 5.9 and a small Howard’s Hyd cam @ 220@050. The other 5.9 is making use of an old Crane Hyd cam @ 236@050. I’m just screwing some crap together on a temp basis for fun until the LA’s are done.
