milling stud bosses with Hogan cutter

Magnetic Drill Models HMD904 / HMD904S / HMD904K / HMD904C

I been contemplating installing screw in stud in my 062 vortec heads. I thought about purchasing the comp cams stud boss cutter but then starting thinking about using a Hogan cutter. I have access to one of these from borrowing from employer. My thought was drilling a heavy plate to bolt to the existing rocker stud and doing one boss at a time. I might have to use a couple different size bits to get the boss milled completely depending on the size of the boss thickness on each side of the rocker stud hole.

I'm not saying I won't/wouldn't purchase the comp cams cutter but doing it this way would save some money. What's your thoughts?

It's a bunch of time fabbing up a angle plate to bolt to the intake manifold face of the head and be the correct angle to match the studs for the Mag drill to sit on....but it could be done. Just depends on how much time you want to invest making one. I'd use 3/8" plate,and probably 3 gussets to prevent flex and chatter.

I can't see a way to get it solid enough on any kind of plate bolted to the stock rocker studs though, The Mag drill is heavy, equal to or heavier than the head itself.

I didn't even think about a plate bolted to the intake bolts. You got me thinking now. Thinking it'd be better bolted to the exhaust bolts to expand the use of the plate to non vortec heads for future use. Hmmmmm......

Sure might be better that way...I didn't even think about the Vortec pattern, I was thinking older SBC pattern on intake face.

Reason I thought intake side is years ago I fabbed a plate bolted to intake port face to allow head to sit at the correct angle on a drill press table and do threading/boss milling work.

That is the simplest correct way.. Use a drill press and a Blair/Hogan cutter bit that just covers the OD of the boss. Cut to dimension. Then take a sharp small chisel to break off the small amount of material left around the guide hole. Usually snaps off clean with very little hand file work to finesse the job// I have made a leveling jig for the head from 2x6 lumber, deck screws and a couple of C-clamps

Started working on the plate/jig after work. I got the plate that bolts to the exhaust side fabbed up. It took me some time to get all the holes in the correct spots. The first plate I made I just stuck my calipers in the bolt holes then added 3/8 inch to get center-center but that didn't work to well. It took me a minute to figure out what I did wrong but then realized I was losing the thread depth in my measurements. So I threaded some inch and a half bolts in the holes then measured the shank of the bolt. The two center bolts I drilled to three eights then the four outer bolts I drilled to 25/64ths. Plate bolted up fine then.

I have an old 882 laying around that I'm going to do a test run on. I figured I'd do every other stud then lay a straight edge along the studs to see how close I am.
