I have a 370ci motor 8.5 to 1. The machine shop who did my motor "midwest engine tech" same guys who does finish line performance engines said he needed to know what head i was goin with so he can order my pistons. well at that time i was going with dart. The motors done and i been reading about the flow numbers of the l92 from Livernois motorsport, Intake Flow Rate 360 CFM Exhaust Flow Rate 245 CFM @ 625 lift. I know i wont get that much cause im at 610 but Im impressed. 1,700 basiclly. Not bad compared to the AFR.
Set up 370 ci , 610lift 115 roller cam. Morel hydo lifters. 91.5-94mm turbo. Custom turbo kit with 6.0 headers. th400, Im shooting for 1k hp at the wheels.

My question is can 6.0 headers/ stock manifolds can be used with l92 heads? By my pistons being custom for dart heads im assuming hes talking about the valve angle cut in the pistions 15* valves can i use L92 heads? Are there any lifting problems with the L92 heads? Whats the most HP you guys seen with these heads under boost? I have been doing searches and seen a lot of guys N/a using the heads but i havent found any under boost using the heads. thanks

not to many people i know with FI have used them YET. i think they will be a good head though.
the headers from an ls1 will fit up just fine, no differences there.

I like mine and they seem to help my combo make good power...

I asked a few shops and they said the deck is just way too thin, but I ve seen some guys here using them well past 700rwhp. Need to buy some heads too, probably picking up some AFRs tomorrow b/c the thicker deck.

all depends on power for a street/stip car i'm sure they work well and red beast is hold 12psi.

can they hold 15psi maybe, but they won't hold the 20/25+ psi the race cars need to run the low numbers.

I believe the deck height is the same as LS6 or 317 heads.

My old 317's held 17-21 psi, but mostly saw 18psi/144 runs.

I talked to Mike @ Livernois, Deck thickness is same as other Production heads. Didn't Harlan go 8's on a production head?

I think Harlan went 8.29 with stock heads.
