Say what?

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.

aluminum heads have thread in studs, iron heads are press fit.

No like we said about just undo the rockers and studs then put the guideplates on and then the studs. There is not machine work that needs to be done

It would help if we knew what heads we're dealing with.

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?

Jake
