Somewhere, I read a thread which I can't find now, that stated if you mill .100 inch off a 3836850 head from a 261 and recess the valve the same amount, you would have the same thing as the most desirable "848" head. Can anybody verify or has anybody ever milled a head this much? I'm building a 261 and I have not been able to find a usable 848 head. My machine shop is skeptical of cutting a head down this much. Your help, opinions, and or insight will be greatly appreciated
