Just wanted to close this out with an update. I chose to bypass the 'diagnostic tear down' and apply the $500 to a new 131 short block. It was the right decision as it turns out the the valve spring broke (good guess KGB) and then the piton hammered the valve into the rear intake port. The shrapnel then got sucked through the throttle body and damaged the other piston. Is it rebuildable? Probably but I think it probably caused other damage to the cylinder, valves, etc. and I wouldn't feel comfortable riding a potential time bomb far from home. Thanks for the help!

RivRaptor:
That's a smart choice unless your gonna do the work yourself and have a good machinist handy.  Nice excuse to up grade!

lopezfr1:
Yep. Not a win/win but I'm sure the upgrade will be fun!  ;D
