Sounds like a good head. So a couple of questions: There doesn't seem to be a lot of Magnum intake manifolds on the market so isn't that drawback to using these heads?

Also, given the intake limitations, is this head a better head for a stout street small block than the large port aluminum commando heads?




Large Port Commando is still my favorite "street" type SB head. It is head and shoulders above everything else in terms of flow and quality of casting. Only drawbacks it has are the W2/5 race rocker setup and they are more $ than a Magnum R/T or a set of E heads.


OH and here are the new #'s hot off the flowbench, on the left is the intake #'s from before and on the right is a mirror port with the short turn layed back more as I had discussed previously.....

LIFT----OLDPORT-----NEW
.200"---148.4-----137.3
.300"---208.7-----202.5
.400"---243.2-----242.2
.450"---252.5-----248.4
.500"---255.6-----256.0
.550"---259.1-----265.0
.600"---268.4-----273.3
.650"---276.0-----279.1
.700"---281.2-----285.7
.750"---N/A-------288.8

Did exactly what I expected, lost low lift and traded it for gains in the high lift.

I'll be sticking with my original short turn shape on the next 6 cylinders.....
