SBC How to screw in rocker studs.
HTML-код
- Опубликовано: 15 сен 2024
- Had to take apart a turn key 355 purchased from five star engines after breaking two pressed and pinned studs. Both snapped at the spot of the pin since they were not drilled straight. Tapping for some ARP screw in's and I'll be good to go.
Save yourself a world of headaches and dont buy from fivestar engines, they installed an extreme energy cam and dual valve springs and yet dident bother to upgrade the studs for me. Thanks again fivestar for your shotty workmanship
Great way to break your tap dude. That's why it is important to go in a couple turns and back off one turn to keep the chips from binding. Taps do break and when they do you have less hair on your head at the end of the day. Taps are made from super hard steel and will break like a biscuit and it is hell to drill them out and remove the broken piece. It's machine shop 101.
That tool is meant to be used with the screw in studs that don't have a hex portion for a wrench. Those studs are supposed to have the bosses machined whether you run guide plates or not. You run the risk of running out of thread for the rocker nut to adjust the valves doing it this way. If you had no problems, cool, you got lucky! 🤘
So you're saying the stud is too high and you won't be able to get the rocker arm low enough for good geometry?
@@sawyerbarnes7439probably.
@radkins80 thanks for the response. I just don't wanna add that to the machines shop bill if I don't have too.
@@sawyerbarnes7439 they make specific screw in studs just for this job that you can screw right into the boss after taping with this tool. Great upgrade for a good set of stock heads.
@@sawyerbarnes7439 or another option you can do....is to drill through the boss AND stock rocker stud and roll pin them.
Amazing someone who can use the guide tool right. Amazing few videos that they don't
Did anybody else hear Ted in the background.
Yes, Stranglehold is very groovy.
Stranglehold baby!
Music to screw by
They do have screw-in studs that won't force you to cut the bosses down. They don't have a hex head to tighten it down, so you'll have to use two 3/8-24 nuts to do it. Uses the same size tap 7/16-14 to tap the bosses.
Yes
I was always taught in HS Machine Shop to back out the tap after cutting about 3 turns. I would use Permatex 2 on the stud threads to keep the coolant out.
Pretty neat tool we never used to have that back in the day that works pretty good I always try to do it another set of heads cuz we did it by hand but yeah it's pretty cool thanks man
355 Stroker?
you bet they did. ended up having to buy a boss cutter and milled them down about 3\8ths of an inch. then had to re-tap alll the wholes again. was a bitch, so learn from my mistakes.
Perfect background music
tap em out with a ball pein and a small punch or finishing nail. then use some washers and your rocked stud nut to pull it out of the boss. if the stud is broken inside the boss you should be able to just hammer it down into the waterjacket without issues.
A 355 stroker huh? Ok bud.
Lol it may have been a 305 or 307 lol lol. Could have been a 383 and he de- stroked it lol lol. 😂
did the rockers bottom out on the hex of the new stud?
Great video I must say. Thanks a whole lot. What brand is that tap handle and where did you purchase it?
Nice vid man. So you did have to mill down the boss?
FYI: you actually don't need oil when tapping cast iron.
you dont need food either or air but it helps you live,fyi
Seems dumb not to use oil no matter if u have to or not lol it helps lube the cutting edges and even if u don't need it for the head (which I believe u should) u still wanna use it to get more cuts later from your taps
No but Tap will last longer
Those Studs will not be Straight when he's done GUARANTEED !! That stuff needs to be done on a Correct Head Machine or Mill . Let's see Straight Edge across those studs when Finished!?!? if you want a Nice running Long Living motor Don't do it that way.
trillrif axegrindor You 100% NEED food AND water to live. They are not optional, like the use of oil when tapping cast iron.
What kind of tools you need to do the Threading on the 350 Chevy heads
Thanks 😊
Rocker arm bosses seem a little tall for screw in studs
they are I love these youtube machinist and mechanics
What’s the little square tool called
cool how do you get broken studs out
how long did it take you to realize it's not as simple as that?
where did you get the tap guide tool?
You can get the tool from speedway motors around 20 bucks
same thing just happened to me same pins in studs how did you get the old pins out?
so you didn't have to machine down your stud bosses to make up for the rocker stud nut?
did your stud still pull out even though it was pinned?
yeah I had the original motor made by five star engines. just a little over bored 350. they pressed and pinned the studs and I eventually had two snap off right flush with the boss. had a leaky rear main seal from start. after having the motor for 6 months and only a few hundred kms's Started to lose oil pressure. main bearings started to score which eventually led to me snapping the crank in two.
five star did not stand by their warranty and was one of the worst experiences I've ever had.
355 stroker?350 bored .030 over/stock stroke Any how AWSOME vid answered my Question if I my self (garage engine builder) can yank the shitty press in rocker studs and screw in new one with out paying a machine shop to do soo...save myself hundreds of bucks

Friend I put some screws arp in the head of the 350 and the balacinho can not regulate the system aibsa original rods and tuchos, the problem and that it slopes in the base of the screw not saying much and giving slack in the rod.
you have to cut the bosses down
Did you really say "355 stroker?" Yes, 8 years later I felt the need to ask this. Dude doesn't know what a stroker motor is.
Could of been a 305 originally, 355 stroker kits exist
And about the boss getting in the way...Could'nt you use .200 longer valves and .200 longer push rods??? If a guy where going to run a cam with .650+ lift See what Im saying or am I taking shit
Press in studs was a stupid idea to begin with.
3:20 THAT'S WHAT SHE SAID
wrong style studs
