How much power are you making on a set of stage 3r ls6 heads?Im having a 408 built by eric hk racing and its being built around et245 heads.A local texas true ten.5 limited street class i would like to run sometimes requiers a stock head or afr 225,tfs 23* heads.So how much power will i be losing by going with ls6 stage 3r,over et245 are the afr/tfs ?

 

You'd definitely be loosing a ton of high end power by going with the ls6 over the AFR 225s

 

I dont want to lose any top end power.later i willbe spraying.I would love to see some more ls6 power#'s one of the most powerfull na 408 was at 600 rwhp was running ls6 heads.
