Default anyone make aftermarket L-92 head
i need a set of L-92 heads. i bought a beck sheetmetal intake but they are built for L-92's. the only problem is that its going on a 434 with f1-r around 18 lbs. they said the deck was to thin to put gm heads on it what other heads will work with this

Check out the Mast "Black Label" Heads MastMotorsports.com. They have a new 12 degree LS3/L92 head has thicker then stock decks on it.

For as much as your goinf to spend on the MAST heads, Id just go ahead and get a set of All Pro heads.....

What are you looking to spend?

Either way you go, Mast LS3/L92 or All Pro Cathedral you are going to need an intake manifold to keep up with them. And no, just throwing a FAST on there will not be adequate.

What about LS9 heads? They are L92/LS3 style heads that obviously take boost?? Could you have someone CNC them for you?

The Fast LS3 102 intake flows very good and I'm sure it will be adequate for the big cfm cylinder heads I'm about to get. The Mast heads dont flow any better then WCCH or PRC ported LS3 heads the only advantage would be the thicker deck which would be great for a 300- 400 shot or 20lbs of boost.

Yeah true story man i have TSP Ls3 heads they pull strong N/A from 3500 to redlind but my curve is really flat with a stock L/76 on it. I really need a vic jr. and a 4 barrel TB to keep up with the heads an cam cuz it's so big. I'd going with the Ls3's milled out.
