Both of them have a 590 lift and require headwork. I currently have a s&s 510g and no headwork. I want to move up but I don't know which one to choose or do I just go with the guy doing the heads and ask him which cam works best with his heads?

 

I had the Woods 6hg in my 95". That cam works. It was in a Road King Custom and I toured all over the place 2 up. Plenty of power.

I sold that bike and got a 2010 Limited. The 103" can't hold a candle to that 95" with the Woods in it.

I had it set up with 10:1 c/r ported heads w/ a Fat Cat quite baffle. 100/103 build. Never had a pinging issue at this c/r. I suggest not going any higher because the gas today is s**t.

I also had a DME 590 cam in it for a while, it was close, but the Woods pulled harder.
