Stripped down a block today, unscrewing the studs a number of them wobbles as they unscrewed initally I thought they had beem bent.However on cleaning the threads with a tap it was apparent some holes had not beeen retapped squarely, to compensate te studs had been bent to an upright position
Cleaning the block face revealed other bodges, 3 of the retapped holes are about half a hole out.
Is there an engineering drawing available that gives the correct position of the studholes so that this can be set up on the mill and the holes redone at the correct centres.
I know I could just measure the holes in a cylinder head, but a proper drawing would be better.
I could just get another block, but most seem to have issues of one sort or another.
Any help greatly appreciated.
