TFS Heads: to mill or not to mill...
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).
