138HP/135TQ out of my 120. Impressive what you're doing with the hand porting and attention to rotating mass. You don't mention your compression, but I'm running the CP forged 11.3:1 and have the FM level B heads. It's been a very reliable build going on 3 years and 20K+ miles.

Strych9,
Very impressive, a nice flat torque curve and then a bump towards redline. I think compression plays a good part to making HP. I'll be at 11:1 compression, and I'll be using the TTS200 camshaft. Heads will be stock, although I'm going to closely inspect the valve seats and bowl area to see if I can blend any sloppy machine work, I have not looked at a set of M8 heads yet. I'm not talking about porting, just blending if needed, a small clean up. Exhaust will be Fullsac header with Rhinehart DBX 4.0 using a set of DK custom Thunder Torque Inserts. I set target at 120-125hp but will be pleasantly surprised if it has more, looks like it may...
