243's To TFS 215's Do I Need To Re-Flycut?
I flycut my pistons for 59cc 243's on my old setup, but I just got 59cc Trickflow 215's. Will I have to flycut again because of the different chamber angle?

With both heads being 59cc, you'll have better/more clearance with the TFS heads because of the valve angle. So, if your going from the 243's to the TFS heads, you won't need to re-flycut because you'll actually have more clearance now. Because of that, it will cause a change in your compression.
