Just pull out the old rocker stud, install the guideplate, reinstall the stud. Done. There's no machining necessary. Stock studs are screw-in.
Just make sure you center the guide plate before tightening down the studs.

The Best V8 Stories One Small Block at Time
On another Forum, a guy just spent $400 to have his stud bosses machined down.
He'd bought screw-in studs and screwed them in (so apparently his were already tapped). Then saw that he had a rocker arm clearance issue and the guys on that Forum told him he had to have his stud bosses milled down.
So, $400 later . . .
I'm presently trying to find out how all that came about.
When I wanted to install screw-in studs in my early 86 Vette iron heads, I just had the stock press-in studs removed and the bosses tapped while the heads were in the shop for a valve job, new guides, etc.
What am I missing here?
