    Picking out heads.

    I Need some advice guys, I want to have a mtoro built but im not sure which is the best set of heads for the build. IM wanting a ls2 stroker built, eventually in 5-10 yrs. i wanna twin-turbo/supercharge it but for now its staying n/a. the base price for the build is about 7500. head prices are as followed, if no price is on the head its included in price.

    Stage 3 6.0L 72cc heads
    237 Aftermarket Castings heads (+$400)
    Stage 3 LS6 64cc Heads
    L92 71cc w. rocker arms and pedestals
    Stage 2.5 LS6 heads (-$400)
    Stage 2.5 6.0L Heads (-$400)

    Maybe someone can tell me the difference between stage 2.5 and 3. and give me some reasons why certain heads are better or worse.

    Thanks in advance guys.
