Re: Switching Head bolts
The 'mechanic' is a full time engine rebuilder. I just called him and he
said no problem to switch the two bolts. Just torque it down to the correct value and you'll be set. He's the one warranting the job so I'm happy.

Re: Switching Head bolts
He already has a mis match on the head gasket Steve.
He is putting a 4.0 head onto a 4.2 block. That makes it a 'twitchy' installation to start. 'I' would not take a chance on blowing a new engine for something that dumb. Maybe that is just me, but.... If I forked out in the order of $2K plus I most certainly would not take a chance on a head gasket that 'might or might not' be compromised. I have assembled and have seen assembled a whole pile of engines over the years and most people, let alone 'mechanics' stop and think when they find 2 head bolts that are nutted studs instead of bolts. It seem 'logical' that these 'strange' bolt like things should go somewhere special eh? One is for the bracket, the other goes on the back drivers side corner for the ground strap to bolt onto. In all due fairness poor Bill's 'mechanic' is kinda on the brain dead side to just put it together wrong without checking wouldn't you say?

Re: Switching Head bolts
Hi Mike,
Cut him some slack, I can see where an engine builder may be confused as to where a head bolt with the stud would go, I don't know of any book that would tell him where fifty years of different brackets would attach. Anyway, the installer should be able to swap bolts.
