looking at some of fast68plymouths articles on the tech board, i was wondering if i could support 500 horse with the heads i have.

links i used for comparison: http://www.moparts.org/Tech/Archive/bb/4.html http://www.moparts.org/Tech/Archive/bb/40.html

my heads: 906 castings, .060 milled off. 2.14/1.81 stainless valves w/ back cut. 3 angel valve job with bowl porting.

from fasts article, and the work done to the heads i have i would assume they are in the 250cfm range @ .550 lift

aluminum is a bit pricey, and these are already done. just wondering if i can get what i want out of them

thanks for any help!
