Anyone going with ported Edelbrock Magnum heads for their 408? It would seem like the better chamber design would be worth a little bit of power.
Hughes has a nice rocker arm setup so that solves the one concern that I used to have. The heads can be drilled for LA or W2 intake manifolds so that solves the intake issue.
Anyone running ported Magnum heads with a Victor or W2 intake? I haven't seen any pictures yet but there must be a few guys with the combo.
onebaddakota runs/ran a stroker eddy magnum setup quite effectively.

Dulcich tested one also.

Ported Eddy heads on my Magnum based 408. Runs 11.6 and change up here at 8000' DA.
The Hughes shaft rockers only work on Iron heads

Having the heads drilled for the LA or W2 bolt pattern seems like a good idea. There aren't a lot of race intakes available for the Magnum bolt pattern.
I don't understand why the Hughes rocker arms won't work on the aluminum Magnum heads. Guess I'll have to give them a call to get the details. I assumed the bolt pattern was the same between the aluminum and iron heads. Must be something that is different.
I if remember correctly the eddy magnum heads are set-up for small-block chevy rockers,
