The Magnum heads are all the same from the OEM or aftermarket except the Magnum R/T heads with 2.02/1.60 valves and better ports in and out and added strength if ribs like the W2 heads.

His heads may have better ports to start with and normally are reported to port out better than OEM casting.

Doesn’t matter too much but magnum r/t heads are 2.02/1.625 and came with stainless valves. Not sure why they increase the valve size by 25 thousandths.

For the OP, the build sounds fine but I don’t think it’ll get you to the 450 your looking for.
