These are the same heads that picked up 29 rwhp over a set of stock LS6 heads. They can't be all that bad.

Let me know if you want to let go of the darts, they might be enough head for when I build my new motor.

That torque is ridiculous and makes a little more than my blower setup
We'll see what happens
You made a couple less horsepower and 50 more rwtq than somebody's 383ci single-plane-converted AFR 220cc 250/260 LT1 car that we know. 
Good thing you went to the right place

Nice numbers out of a LS1. SHould be a blast to drive.
Kraest if you are comparing an LT to a LS learn what apples and oranges are.

I used to own a 396 LT1. I'm quite aware of their potential, thanks.
There's no reason someone can't make power with a $10,000+ solid-roller LT1, unless the reason is poor R&D.
The remark was made in jest for Mark's humor. Not sure why you're calling me out?
Alan did another great job as usual, wait till you see my motor plans for the camaro mark

Update!!! I just got the final tune in the car and picked up a few more ponies. I am up to 487 rwhp and 473 rwtq. The car still only has 1600 miles on the engine.

As for track times I managed an 11.4 @124 tonight taking it easy on the car launching at 3000 rpms and shifting lazy.

They do flowing on a wet bench, so you cant just go from CFM either. (At least I tell myself that
)But I agree there are probably nicer heads out there now (Maybe not at the
same price point though)

I plan on moving to some ported LS6 heads. I feel the 205 intake runner just does not have the volume needed for the cubes. It is pretty obvious in the tuning and graph that it is having trouble filling the cylinders.
