On Stealth heads......More performance oriented seat work and a basic bowl and SSR tweak can yield 20cfm gains(at accessible lifts) on the intake side.
I've watched it several times and yeah eventually getting trickflow heads but these will do for now.I would have a competition valve job done first. There's a You Tube video by Weingartnerracing where he inspects some 440 Source heads. You should watch it. Some good info.
This is a nice cam and is capable of knocking on 500hp inn a 440 with performer RPM heads.
