Just a reminder that I wasn't saying I didn't believe you when you told me the first time. If I measure out with the adjustable pushrod the correct length, I can order or purchase a full set of pushrods that will fit my build. Here's another question: Can a head use both pushrod oiling with early rockers and through shaft oiling at the same time? I have my own thoughts, but what do ya say And yeah, maybe I'm feeling lucky if I learn the rules and then play them. I hope I'm reading the right rule book though.
I quit. When tightening a rocker stud, it snapped off in the head. I get one good drive in. And that's it for now. I hate this so much This is ridiculous Are the rocker stud holes blind? As in, no oil to them except the first one on both sides? Damn torque was 25 not 45
To late to give up now! Take a break then head down and solve the problem. When was the last time You met a mechanic that did not have the patience of a saint.
Jon, Not the last thing you will break. Pull the rockers and pushrods, plug all the holes with paper towels, enough to prevent crap getting by, but not so tight you cannot get them out. The get someone to assist with a ship vac and get a pilot drill and EZ out. Most likely the bolt shank will come out with minimal effort, unless it bottomed out and is compressed upward against the threads, but even then, you just want to work it slowly, and an impact drill set on the lowest setting may help. Let me measure a stud bolt and I'll post the size EZ out you will need.
Use a somewhat strong magnet along with the vacuum to help to keep flying debris from not being sucked up by the vacuum. Maybe a little overkill, but all it takes is one small piece to get where it shouldn't be.
You guys are the motivation, if not myself, I'll fix it for you guys I'm so dumb, but hey I guess we all have our moments

Hang in there John. I made all kinds of mistakes when I was 19, believe me. Wish I had a resource like V8 in 1975. Walk away from it for a day or two.
If you don't have a screw extractor set yet, try to buy one with counter clockwise drill bits. A lot of times just drilling with the bit will catch the bolt and unscrew it for you. My Mac set was $50 with 5 sizes of extractors and counter clockwise bits, but that was 15 years ago.
I don't think my electric drill will drill counter clockwise, unless Ive been missing one of its major functions.
John, I'm not checking in as often as I'd like, but I do enjoy watching your progress when I do. Please ditch the "The more I think I know..." tag in your sig. My first impression of you is quite far from dumb. You've already heard a bunch of advice (and it will always be conflicting), and have done a fantastic job working toward what you're after. Never stop. I'm impressed with the progress, big time. The car sounds great! Broken bolts and bolt extraction happens to all. More fix it stuff will always come. Go get it done...you'll be pleasantly surprised when you have. Watching and reading here, you're gonna love the rewards for the hard work, and more importantly, figuring stuff out by yourself along the way. Devon
Ahemmmm... tongue in cheek, take a 3/8 dowel rod and whittle it down just a bit and press it onto the screw and turn it out. Sometimes the harder fasteners break off in a clean and oiled(!) hole and once the head is off, the stretch is relieved on and it will just turn out. If it were an ex. manifold bolt that broke because you didnt tap the hole clean and use anti-seize and forced it in anyways and it broke, you'd deserve a bitc, ah er, pimp slap! Seriously, I rag at guys who dont clean the holes and especially wire wheel the bolts all the time, and when they bust, I look the other way. Just get in and get it! ws
There is a good chance what Bill said will happen. Sometimes they are broken and will just spin out if you work with them. Next thing to try is the Irwin Screw-Grip that Michael posted. I use them at work all the time. The drill side of that item is a REVERSE DRILL BIT that you use first and sometimes the piece of thread will back right out just drilling it out. You can usually find them at any decent hardware store under various names. You will need to get a battery powered drill with REVERSE capability. Those extractors are not meant to be spinning around at 1000 rpm. Too easy to screw up with them and an electric drill, even a variable speed unit. Make sure you get at least a Grade 5 replacement 5/16" bolt for the rocker hold-down. Get the correct length because too long and it will bottom out causing greater headaches. Maybe replace all of them if they have been over torqued. I don't think you will have a problem feeding the rocker arms from both directions because once both oil feeds meet in the rocker arms they will equalize. As far as I know you cannot get pushrods with a 5/16" ball on one end and a 3/8" ball on the other end and I'm positive you cannot get an adjustable checking pushrod setup that way. I would say you can use a standard 5/16" ball on both ends pushrods for your setup and should not run into any noteworthy problems so you could use a standard checking pushrod for that. I think with the price of the not really correct ends custom length pushrod and the purchase of an adjustable checking pushrod you're not too far away from the cost of the hybrid adjustables. The only problem I see about your contact with TA is that the guy on the phone apparently didn't know enough to bring up the subject of the hybrid adjustables. Making a blanket statement about lots of guys doing it doesn't cut it when you already have a product developed to guarantee there is no problem. I would've asked why they made them. Don't trust anybody 100% of the time.
They DO make pushrods with a 5/16ths. & 3/8ths ends. IF you can't get them from T/A I know Smith Brothers make them.
Make sure you get at least a Grade 5 replacement 5/16" bolt for the rocker hold-down. Get the correct length because too long and it will bottom out causing greater headaches. Maybe replace all of them if they have been over torqued. Those arent ROTM bolts (run of the mill). Theyre a special bolt with a specific OD -about 3/8? with a very specific length, and a 3/16 6 point head on the top. They also should stop and tighten when seated due to the sizing and shoulder depth under the bolt heads. Take air and blow the crap clear from the holes. They should be oily enough to insert unless a valve job and hot tanking was just done. In that case a healthy drop of oil on each should suffice. If you really feel the need to torque them start at the center and work yer way out. Theres only 4 per side there Von Braun! ws
Also make sure you use the collars that go over the shafts (helps distribute the load). Without them you risk cracking the shafts. I'd be a bit concerned that the over tightening may have already done damage. Been there done that.....and I was ten years older than you..........
