I do not know who did the work on the heads, but the port work looks quite good. Definitely CNC machined. They also come fully assembled with BTR .660 lift extreme dual springs with chromoly retainers (Speedinc set up the heads).

The car made 390rwhp with a small 224/230 speeding cam. After looking thru the tune, I think another 10rwhp could have been squeezed out of it with tuning. The dyno was done at Speedinc about 500miles before the bottom end let go, so who knows if that had an impact as well.

thats exactly right. Opening up the ports usually exposes the bottom of the rocker bolt hole on the intake runners. You use thread sealant on the rocker arm bolt. FYI, both of my CNC LS3 heads (Advanced Inductions and GM Ported) have these holes.
