So.. no leakdown numbers at this point?
If so, that'd be my next step before pulling the head.
My hunch is still on the valvetrain. There have been cases where a worn timing belt has failed on startup and that's enough for valves and pistons to collide. All B-series motors are interference, so even a glancing blow at 500 rpm is enough to do it.
It's a damn shame that you found out about this now, but I'd still stick with the car. :hs:
