would it really be worth it?
What drawbacks are there to L92 heads. I know you need new rocker arms, but $140 isnt bad for stock L92 arms. Do you have to block off any DOD stuff?
Am i going to have to pretty much abandon everything from my 98 LS1 and start over with all new stuff, like balancer, lifter holders, valley pan, sensors, and all kinds of other stuff?
I hope im not hijacking this thread.

I checked it out, but 16 pages of nothing but people asking questions is hard to navigate through. I was just hoping that someone could answer my questions with a simple yes or no here and there. The search feature doesnt turn up that much, or at least it didnt for me.

So are you looking to go 6.0L iron block or the LS2 block? The L92 heads will bolt on without issues to either. One thing to be aware of is that for those big intake runners, you'll need more air coming in to excite that runner. You can do that by spinning the engine higher RPM's (build the bottom end correctly and it's very do-able) or by adding some more cubic inches. Like stated, for a little more $$, most would agree that the 408ci powerplant will be a blast over a stock 6.0L! You will need to use regular LS series lifters, trays, etc for your build. Since you're only using the L92 heads, you won't have to deal with the active fuel management (AKA: DOD). I think that covers most of your questions, but feel free to PM, e-mail, or call me if I can help you with anything else! We also have a wide selection of built shortblocks available that are custom built to your needs!

As far as cam choices go I bet a 11:1 6.0L would respond very well to a short duration high lift split say 224/232 .632 .643 on a 112 LSA ground on Comp LSK lobes.
Get with Matt at SDPC for any L76 parts, he’s a great dude and if by chance you find yourself in Lubbock TX swing by and he will give you a guided tour!

Im doing a 370 with the l92/l76 setup as well and would like to hear what everyone else thinks about the questions already asked. My compression will be around 12.1.1 and im trying to find a custom grind cam to suit the amount of nitrous im going to throw at it. It wont be a daily driver so i want something ratical.

Theres a good write up in Car Craft for April and May for a 6.0L and L92 heads compared to the stock heads with a mild "Hot Cam" and then a Comp 281HR. All tests were done with a stock LQ4 6.0L longblock .
Those are pretty good numbers for a 9.4:1 motor...
