I need help.

I broke all 3 studs off my manifold so had to drill out the bolt and
rethread with a tap.

When drilling out the broken bolt, I missed the center and also
drilled at the wrong angle.

BTW, you didn't say how far you had drilled. Just a bit, or more than
an inch, or what.

Any hints at making a perfectly aligned hole right thru the center of
the bolt at the perfect angle?
