A lot of people run ported 5.3, LS6, and aftermarket cast heads. I actually don't see very many ported LS1 heads....
Anyways, I think if you could get them to flow around 300 (+/-5) with the porting and install 2.02 and 1.57 valves along with a 5 angle valve job you will see a good 20-30hp. I may be a little off, but that's my guess!
