ArizonaGN stock replacement heads

[deezdad]

w/ prformance valve job bead blasted checked for cracks etc... Anybody running these heads and/or know how much of an improvement they are vs. stock? And how well they would work with a smallish combo TE-44----36# Ford blue tops---194/204 cam etc...Thanks,-Dan

They will be enough of an improvement that 36lb injectors will be max'd if you turn the boost up.
