Well, it looks like that 68 400 I finished the mechanical restore on in January blew a head gasket. Water is coming into at least one cylinder.

I checked the head bolt torques and they were all loose by about 1/2 to one flat. It has been suggested by a buddie of mine that the old head bolts might have stretched. Has anybody had this happen to them? I've always reused head bolts on all my Chevy motors in the past and never had a problem.

The machine shop said the block didn't need decking when I rebuilt it, so I would assume they are flat. Heads were milled.

If I need new bolts, where can I get them? Ames' bolts don't have the studs on them.
