drag race car only, 496 RB, solid cam .650 lift-

Buddy of mine has a pair of nice fully ported 906's w/ 2.14 1.81 valves, milled to 84cc, dual springs, etc. He wants to trade them for a pair of stock aluminum Stealth heads. There is no option for porting these this year, plus having to change the springs, retainers, locks.

I'm trying to convince him to stay with the 906's for this race season & then buy much better heads next year (such as the new Trickflow race version, Indy's, etc.) then sell the 906's.

I think he'd be going backwards by using the Stealth heads "as-is". I don't think the weight savings outweighs the HP gains of the ported heads. Opinions ???
