I can't answer the cam question, but I can maybe help with the lack of go down low issue. I had my cam reground by Wade.

I am running G161 from a TX with seriously shaved head (prolly 9.5:1 comp or more) which put the cam timing out.

Thankfully I have an adjustable timing set, and the guy who set it straight told me it was 10 degrees retarded. It was flat as a tack and needed hard revving to get going, even then it didn't seem right. Now it goes like the proverbial, biiiiig difference.

So maybe if your head has been shaved the cam is out?
