What u wanna know.......I'm a FED factory ls3 stg1 head guy and have refered a whole lot of people on Chris's program.* Been dealing with Chris a while now. You've just got a better head so mores to be expected with a better valve layout. 800 can be had with the factory casting from Chris ....you have a better casting✓ 418 13.2 compression 800+ @ 7800 ^. Again u have a better casting. Intake choice is key....

I want to know if anyone has a build with them and what are the results 
I have a Goertz1 intake, posted pic in Darth's thread. Stock sbe ls3/stock heads&CR is still climbing hp at 7400 with a cam not made for it. I run a baby 231-236 TSP cam. Been nice so far even with the TQ loss hit; 519rwhp
I want to know if they are going to do more than TFS 255 numbers since I have most of supporting parts; T&D rockers, solid cam spec to come(240-254ish 675'ish lift), higher comp ratio limited by 91oct.

Heres 1 thing ....swap the heads on the same combo would be = or be better ? I know u want a example of the heads being used....I keep it simple if the heads were swapped would be = or better.
I copied 2 people with my own twist. I had a good reference and baseline. Reason for 2 heads.

590... look at the difference in the build. Your intake helps .....More compression? Bigger Cam? You have a reference. Vaccum pump,ewp, etc...adds hp.
Plain and simple look over the reference build & build it better than a stock Ls3 with ported heads and a llsr. Simple!
