Why am I drawn to the aluminum??

Yes,no porting. Brian,got this RHS head dialed. No porting,sweet Ferrea stainless valves,a real valve job. You looking at roughly, 1000-1500 on top of the Edelbrock's price. Valve job,porting are not cheap.

Eddies for roller cam run $830 or so at Summit so $1660.

Brians unported setup is a bit less IIRC so not sure why you're saying 1000 - 1500 extra?

Edit: Brians are $1469 per set, less than I was thinking so maybe a bargain in comparison.
