Yeah, I could see a 20- 30 HP increase on home ported heads if done properly. For comparison, I pulled 34 RWHP more than a car with a TR230 and ls6 heads. I pulled 52 more than a stock headed f13 car, though he was tuned a little rich for the juice. Granted I run a slightly bigger cam. ( XER 232/234 .595/.598 112 +2 )
Those pics look good to me, although I cut a little deeper into the rocker bosses. Also be careful on the left hand side of the guide since if you cut any deeper youll hit the waterjacket. Hard to tell depth from the 2D picture, but it looks like you might be cutting it close.
