heads for 408 stroker

hey guys i need some help. I am having a hard time deciding what head to go with on a ls2 based 408. The cam size is a 247/251 .656/.660 lift on a 111lsa the intake is a ported fast 92. I need to be around 70cc on the combustion chamber

AFR or Trickflow is good advise considering you already have some expensive parts bought. This rules out a set of ported LS3 heads - very good performers at reasonable prices.

Next time I'd recommend buying your heads before selecting a cam. Much easier to grind a cam to match heads than the other way around.
