Tasty lump

One of the exhaust manifold studs broke off flush with the head. Against my better judgement, a friend persuaded me to try Easy-Outs. Of course, it broke off. Now there’s a piece of hardened steel jammed in there as well. Never, ever using them again.

Debating whether to pull the head and take it to the machine shop to be drilled out. Once you’ve got the head off, you might as well..... it’s a slippery slope!

Engine number R 27460 makes  this a 3-main bearing SAE 
engine from 1967.
