I have a set of GMPP true LS6 heads that have been milled .050 that I am going to stick on the car in the next week or so. I'll dyno it again with that being the only change and report back with results.... then I'll have the GMPP heads for sale.

Nice numbers..
I am soon to be doing something simular...glad to see it pays off. with stock 241 heads.
But just out of curiousity, how much do you think the difference would be if you kept the stock exhaust valves in the heads?

The exhaust valves are stock, although the came out of 5.3 heads- the 241 stck exhaust valve is very simular to them, these were just the only valves I had at the time. The heads arent stock nor maxed out, their just a good street head on ported wise.
