Well I've pretty much convinced myself that I am going to upgrade the heads to the TFS 215's. What I am wondering if it is worth the hassle to get them milled or just leave them as is. My current 241's are milled .020 and I had to spec the cam accordingly. So what kind of power am I leaving on the table by leaving them in their stock configuration (64cc chamber).

yea me too, no point in not doing so if your going after a aggressive h/c combo.

So how much with an F13 on a 112LSA and no advance should you be able to mill without flycutting is the next question.

You have to check to make sure but 59cc shouldnt be a problem in my opinion.
