Redd,
Sorry to read of your problem. In your previous post about tight lash I questioned whether you had spec for alloy heads. It's customary to see lash speced at .018-.028 on iron FE's with .006 less for alloy. Your .012 spec suggested aluminum to me with an .018 cold iron spec. [still fairly tight]
I agree with Hotfingers, I'd tear down,inspect all bearings plus crank and cooler if you have one. Look at it this way; 1/8 " is .125." Figure .020-.025 for lash and you've still got .100" of cam lobe [plus lifter face to account for. I think it went all through your system as fine grit. Hope it's not this bad but I'd sure look to find out. See if your builder wants to be cooperative. Good luck and keep your patience.
