[TR] 1965 TR4A - Looking to drill out a stud hole in block. Need recommendations on a drill guide/jig.

Jerry,
As much as I hate to say it, I would source another block at this point. Money wise, a good block would be much cheaper than any machinist cost. Bad news obviously is that Guy is going to have to pull the entire engine. 
Guy, it’s too bad you live so far away as this would be a great group effort to get your car fixed!

A machinist can take the block and set it on a mill or drill press table which should be perpendicular to the drill axis and drill the hole oversize to accept the insert of your choice. But as another said have the block checked to be certain the current hole is not cracked. Fix it correctly and don’t look back.
