ok, hijacking briefly.. This comes back to a few weeks ago when I was asking a bunch of questions about different cams and the Woods 555's or something.. I was talking to my neighbor about it (a machinist) and he was preaching "You won't see the same results unless you get your heads done too".. and although I know how an engine function, I don't know anything about the details..like I didn't know what cams were until i started asking questions.. so my next question..when people say "get your heads done" or "get head work done".. what are they referring to? Like what does it mean? ..also going to google now i guess to study
..to answer my own question, i guess it's to increase the quality and quantity of intake and exhaust.. but like.. what actually goes into doing it?

The heads from the factory have casting marks in the runners.. A port and polish will smooth out the runners to get the extra power. The casting marks make the air and exhaust tumble in the ports. Which cause friction. By smoothing out the ports your air and exhaust flow smoother without all the friction. Which will increase the amount of air that can flow.

37's move tq to the right. 21's to the left, 26's to the left of 37's. Headwork, increasing compression, can increase tq. But, too much compression and it will ping. Especially at lower rpm's, to the left. I'd look into 204's, possibly with a 4 degree advance key. Getting 105 tq in a 95" is setting high expectation without spending lots of $$$. Your 95 tq with stock cams and 95" kit is very good. That is close to what cammed bikes with 95" kits get. So, maybe with your dyno guy it is possible. In other words, not all dyno numbers are created equal.

[quote=DR. V-TWIN;8515139]I'd think you would gain about 10 hp and tq with heads or headwork and the 37. There is a great site with tons of dyno sheets for varying builds but i can't remember what it is right now.
