I'm drilling out a set of 8-bolt FE heads to the 14-bolt exhaust pattern to put on my 390 in my mustang S-code car.
Do the holes that go thru the bosses go all the way thru?
How deep do the other holes go?
I don't want to drill thru into a water or oil passage.

I am going to direct you to -here- as they as a group are much more knowledgeable than I am.

Most likely, someone is going to have to take an old head and take measurements. Not all of the holes are the same depth. And again, it may vary with the 390GT, 428CJ or 427 head.

Cool. I applied for membership to that group, so as soon as it's accepted I'll ask away. Thanks for the tip, looks like a good site.
