my old setup (which is basically yours) except i was on race fuel at 180 psi and I had vf2s with an extra degree of timing, I think the jetting we ended up at off the dyno was 50 or 52 pilot, CEL 4th and 142 main, we also used a 138 main and was safe. I had a 160 in it when we put it on the dyno and it basically was drowned in fuel and made like 38 hp. Im sure lane will hit you back, but when i chopped my 7s plugs when i first built it i used a 150 and they read similar to yours, the rings weren't symmetrical. I upped it to a 155 and it was perfect. I run a 158 tho to be conservative.
