alright, I am cheep and dont want to wait for the shops around here to "free up time" to do some head work on my heads, SO... im gonna do the basics myself. What exactly will I need to be able to put in my own screw in studs and guide plates, accually how do I get the pressed in ones out... What are the chances of not getting them in as straight as they need to be? I got the studs and guide plates, studs on box say 3/8"x7/16"x2-7/16" , im useing 1.6 roller rockers if that helps. Someone either help me please or talk me out of it (tho it prolly wont help).

 

Ya know, doing it yourself is okay if needed...i/e you break a pressed in stud, and you need to get on the road.

Problem with doing it yourself, what should really be done, is that the stud boss is machined flat, so that the stud (when screwed in) has full contact patch to torque down too.

If you pull the studs (which is easy enough with some spacers and nuts) you'll notice the stud boss is "roundish" on top, so when you tap and insert a screw in stud, only a small portion of the "nut" on the stud, makes contact. In this case, I'd be concerned with loosening and the stud breaking.

For all I know, someone probably has made some sort of a tool that you can use with a drill motor, to machine the boss...might be worth looking into and asking around.

 

If you really want to use guide plates, you need to machine the stud bosses flat and square, just like Mike mentioned. That means you should pull the heads to prevent contamination of the engine from metal particles. If you think you can use self-aligning rockers instead and only want screwed studs, you can do it with the heads on the engine if you're careful: Screwed Rocker Studs

 

several people make cutters, i have one from bill mitchell made by manley cost me 100 dollars and doesn't work. i've saw lot of people on ehre say they have them and work great, so i guess i'm a dumbass and can't figure it out. pull the studs with a stack of washers and a nut and just tighten the nut. for the screw in studs i set up the row of stud bosses level on a mill table and take off .42". file the burrs, chamfer the holes. and tap. pretty easy and only takesa few hours.

That's among our favorite sayings in the midwest. There's a turkey season, pheasant season, fox, coyote, varmit, squirrel, rabbit, deer (both bow and rifle) and bear seasons. But, to our chagrin, no DNR season...
