MAST Heads What do you guys think about these new heads by MAST? Flow numbers are ridiculous compared to other ls1/ls6 aftermarket heads.

However, I would LOVE to see what kind of numbers people put down with them.
Keep in mind they are not a cathedral port head like your "other LS1/LS6 aftermarket heads" either.

I am aware of this, but at more than $1000 over the cost of some nice AFR or TFS heads.... these things better put down some SERIOUS numbers! Personally, if I was going to drop that kind of coin on that style head, I would put the money into a new shortblock with a larger bore and just run some CNC ported factory heads.
Yea, I was more referring to the OP's comment about their flow numbers.

These heads would be sick to have, but until the LSXr intake comes out it seems almost overkill, no way a ls3 intake would flow enough to keep up with those high lift flow numbers. Mid lift numbers on those things look sick too...

I'd like to see more on these heads myself . I think they'll make the power and be an alternative to ET LS7 head . Does anyone know anything about the casting other than what's online ?
Big flow means big power, aslong as the runners ain't like 300cc or something lol

they are LS3 heads....not ls1-2....ls3 heads that are cnc'ed by any decent program out flow tfs 215 and 225 heads....big fken deal.....who is bolting them on a 346 ls1 block?????
test 
Did anyone else see the 245cc intake runner size? And 2.08 intake valve? Seems WAY huge for a 346. Wouldn't a 245cc runner be better for a bigger (like 402) block? Seems like they would be great for an LS2 stroker, not so much a 346.
