    I wanted screw in studs BITD but didn't want to spend much money (cheapskate) so I did it like this. Take a piece of 1" square bar stock, measure the center to center of two SBC rocker studs and drill the bar stock with one 3/8 hole to pilot on a stud and the other hole 7/16 to guide the tap.
    Place the block on the head and pull a stud using washers, or even old rocker balls to jack it out of the casting. Now turn the block to the 7/16 side and your tap is perfectly aligned to thread the hole. I used to buy Dorman Products studs, the bin number was V-6 and there was another catalog p/n but I don't recall it. The stud had a raised area to lock it down against when it was tightened in the head, no other machining necessary and at .50 cents a piece a lot cheaper than Mr. Gasket studs.
    Place block on new stud, pull next one and repeat until finished. The most important thing is drilling the holes in the block on the proper C-C distance, but this whole thing is probably not important anymore, I don't think Dorman catalogs those studs now. If you do find some old stock somewhere only the black oxide V-6 stud is Grade 8, don't use plain ones.

    Yep ...after the, pin the stud was no longer an option ( still pulled em out ) , if on the engine drilled em at an angle ,if off the engine more at a straight (see pic).
    I / we used that very same method.

    Stud pulling tools ----one picture shows that you can still buy them 14bucks.
    The other picture is from the don't use obsolete tool drawer.

    These are the only screw in studs to use. arp studs.jpg
    Anything else is just a waste of time. these appear to be 7/16 bottom 3/8 top. I typically prefer to run 7/16-7/16. But these are better than pinning or the cheapo threaded studs that have no real way to tighten them.

    Crane used to sell the tools to upgrade heads for the home builders. There was a fixture for screw in studs (similar to what's described above). One for cutting down the head for guide plates. Another for shortening valve guides and cutting them for PC seals. And another for cutting spring seats for larger valve springs.

    I used them on quite a few heads and never had any trouble out of the results on any of the heads I worked. The tools are still around here somewhere, but I haven't seen them in a while.

    And while we're talking about valve train stuff, don't forget rev kits and stud girdles.

    Been asked -
    *liquid nitriding process*
    on valves...anybody use em yet ?

    The best people to find answers like this are the ones that see the most action...
    That is the guys that make the valves..! Manley, Comp Cams, etc.
    Call them for a realistic answer.

    ^ Sure ask the salesman of Florida Swampland, think he'll steer ya WRONG.
    Sure i agree ask, the makers, but because we can , this is no more than a place to hold CONVERSATIONS ,on subjects that elude MOST people. Do you have ANY (1)st hand knowledge on that process...?
    Please share your use and experience.
    LQQKing forward to your input.

    Well anything in the 180/200 treated range, but those 3/8's still break off.

    Yes they do.... but have you ever noticed , on most broken studs , it is the top part...

    EDIT: And its usually the 3/8th's ones, i haven't seen ANY 7/16th's broken ones YET...

    Pins are ok but I've seen them pulled right out so screw studs are really the way to go imo

    Exactly.... and that why, myself and other builders haven't used that OLD method since , around 1969. For certain we installed the LT-1 , GM studs from chevy, and as better strength rocker studs came available we up graded to those.

    EDIT: well they were ok , at the time, (the pinning of studs)when we had NO other way.

    Well for me the, (1)pc u bolt bar (was not the first type i ever used) did not hold PERFECTLY , sometimes and only sometimes the adjustment needed to be re-adjusted...
    then came along the (2) bar.

    Larry ya didn't say what one YOU like...

    I have both sitting here for my Anglia engine, but I think I'll probably run the u bolt girdle (if it will work on the AFR heads). I really haven't seen much difference in lash changing after the valves are adjusted, and the u bolt girdle seems a little easier to adjust for me.

    But, I'm always looking for others opinions on stuff.

    Never used the spring loaded girdles. Looks like it might make things a little easier to adjust.

    As long as we're talking tools, how about pushrod length checkers. I've had pretty good luck with this one from Manley.

    Stock pushrod was .200+ short for this set up. (Dart heads/.100 overstock valves/Bullet cam).

    Also in the picture, 7/16 rocker arm studs. Cam is .540 lift, solid lifter cam, and he didn't want a girdle. Since it's a street engine and doesn't have a really radical cam with roller cam valve springs, I figured we'd use the bigger studs, matching 1.5 roller rockers and call it good.

    And while standard guide plates worked on most of the cylinders, I had to use adjustable plates on a couple of them for geometry and clearance problems.

    probably not a huge amount of guys "building" engines, seems to be a lot of crate or nearly stock rebuilds, Id have thought race engine building at home was as traditional as you could get?

    I have been looking for a valve spring pressure tester for quite a while, but it seems like there are none availible around here, at least not used ones. It would also make it easier to decide, if used springs are still usable or already too weak...My friend Damir scored a valve spring tester on ebay USA but they seem to be scarce in Europe. It wasn´t cheap either. I willsee if I can borrow his when I build my next souped up engine. The last few times I went with what the cam mfg´s recommended for my application. May not be perfect, but certainly better than what I would end up with picking springs cluelessly without exact measurements...
