road race engine...

The weight savings on the aluminum head would be nice, but all of the aluminum magnum heads are fecking chevy bullshit adapted to fit a mopar.They all have 2.02 and 1.60 valves and you have to run 3/8" chevy 1.6 rocker arms.In stock form the magnums have 1.92 and 1.625 and the combustion chamber and intake runner cc's are close enough that the magnums could easily be massaged to be better than the aluminum offerings.Doesnt seem worth it to loose exhaust flow, and have to run crappy chevy valve train when the damned heads cost $1000 a piece. There's plenty I can still do to get the weight of the front end.
