We run the larger bore gaskets (5-layer 6.0/6.2) on the 317 heads on a ls1 block

Good thread this has answered a few of the questions I had.

Now what about machine work, whats reccomended for the head surface & the valves?

Dont you have to pull the motor out of the car to put the heads on with studs?

Not trying to thread hijack but I think it is on topic for this thread.

Gaskets that are made for the 6.0L, I plan on using GM MLS.
