When I got this engine I was told it had a slight leek from the core plugs or freeze plugs. I’ve broke the engine down and I’ve now found that it was the heads that was the problem. It looks like the core plugs in the head need replacing. Not a problem, the problem I have is Where the studs fit for the plug wire covers. They have been broken off and very close to the head. Any thoughts on getting these out or do I take the heads to a shop and get them refurbished? Thanks for any replies. Heads are 322 Buick 1954. Thanks Tim.
