Re: 485hp slp package Milled 63.5cc combustion chambers raise compression ratio to 10.7: 
I am no expert but if you mill out a CC wouldn't that remove material effectively lowering compression. Milled heads maybe
I think that the cam alone would benefit any LS1 engine. The heads are CNC'ed so I would bet that any of the ----> sponsers CNC'ed heads would be "roughly" the same. With most CNC'ed heads out there I would be concerned with cost before their numbers, b/c there are limitations with CNC'ing. This could be why hand ported cost more, just my .02

Re: 485hp slp package
yes I think those are flywheel numbers. I don't know what percent these cars lose through the drivetrain. I was told my last car lost 22 or 23%.

Re: 485hp slp package SLP numbers are always flywheel cause it makes it look like it puts out tons of power. Although with the camshaft they are using I dont doubt that package would put 400 to the rear wheels.
