I'd check with a vendor. Cheaper price and the valve train can be setup to your application. Virginia Speed sells MAST heads.

Very true. A guy on here got a bad set of MAST heads and the turn around time for a new set was months.

TMTMTL

You guys have a bether option than the mast black label ls7?? Wcch? Afr?

All Pro heads would be the ultimate head, but they are pricey.

TMTMTL

How much they run for a set?

Rise of the Phoenix

iTrader: (27)

I want to say around $3,500+ for a set.

TMTMTL

With valve train or no

WCCH - All Pro LSW-1 Heads = $3,290.00

WCCC - All Pro LSW-2 Heads = $3,817.00

WCCH - All Pro LS7&LS3-3 Retro Heads = $3,267.10

Those prices are for the bare castings.

i see, seems like the stage 2 takes a lot of lift to really see the cfm. .750 lift to be well past 400.

TMTMTL

Motor is also only 434 cubic inches... im not too sure yet.. its a street car, but we will see... 700 hp street car is the goal, always shooting high.

Talk to John Bewley from LJMS about the new TFS 260cc LS7 head. Flows on par with a mast 305 and better numbers in the lower lift areas if I remember correctly. If he sets you up with a pair from TEA they can't be beat for the money. I have the TFS 255 LS3 heads done by TEA and they are very nice.

TMTMTL

what block are you running with the 255 (displacement), are they the genx? also what power level you making (auto/m6)
