See if you can get something from stage 8 locking fasteners to fix your problem with the bolt backing out

You failed to mention valve lash adjustment .. a newbie attempting this maybe not know . No bashing your video just thought it might be more helpful information

Couldn't you change the pushrod length?

I need that tool!

The press in studs are 3/8", which is a hair smaller than 10mm. The 8mm bolts will push in with no problem, so that can not be done. Looks like a custom stud from say ARP with the 7/16" UNC in the head, and 8mm for the rocker with a nut. Probably need the studs without guide plates and the nut on the stud. Otherwise, the pedestal needs to be milled farther down so the rocker and guide can sit on the stud nuts.

Can you give me links for what to buy?

I would try to get the best valve stem seal for the heads. Also the valve cover gaskets can be glued to the valve cover, cork or silicone. This prevents oil from getting in between the gasket and cover.

Do you think This mod would work on 95 ish lt1 heads

I personally love this engine it is a Work 🐎 I have one in a Case 1840 on a farm. Good job on the truck, my friend.

Do I just need the motor to tdc or tdc each piston as I go

Custom pushrods, or stock?

I love machinery but no matter what I get I always want something better. I would of got one but i hate china so I got a used logan model 1922. Going to buy a sureline soon super small but works good.

Two things that stood out. Left the key the chuck and what a mess with all the chips. That punch is not a punch and even hardened! Build some shelfs and organise your shop. I would not leave my car in your care at all. Every 3pm on Friday afternoon you clean your shop and organise tools is what I would do.

if you cleaned the chips up EACH time she will last longer, BOLT it down and level it just might be shocked at the results.

what measurement would you cut the pedestals down to? gonna go this direction on a 305 sbc to get more modern valve train on that older motor.

I love seeing young kids like you guys working on motors. Keep up the good work.

Use a sun filter or close the garage doors, by the way the useful bits are nice if you slow down and explain what you're doing

Pretty awesome

You would have plenty of room if you organized that place.

Great Video. My land cruiser is getting a 4bt soon with a 4l80e

My head gaskets good but Was thinking of swapping heads on my s10 cause I found a spark plug with no nut and a ton of sealant around it -.-

On pedestal style engines you shim the pedestal.

This is exactly what i wanted to know.... Excellent information ( considering i have several of this style 4.3 engine available for scavenging....) wonder how close the 4.3 pushrods are to the right length. 4.3 rocker?

If it works ....should i replace the springs for stiffer ones or stock replacements! Appreciate your content!!!! Thanks in advance!!!!

Assuming....it has a non adjustable valve train!!!

Interesting!!!! im going to try sum 3.4 rockers on a 2001 4.3 Silverado.....!!! It should work right????

Those rockers are $11 or $12 each from Rockauto, so this only works if you have a handy recycling yard.

Why bother, too much tom foolery for the small gain ?

Maybe 7..16 by 14 ..not 20 ?

Have you tried checking ls rockers with lash caps

No way to adjust them!

What kind of valve seals are those?

Hey… you wouldn’t by chance have a video of you straightening the threads on the inserts. Having issues starting them in the die set.

in regards to using LS rockers sketch because of geomeetry.... would installing lash caps help? it makes diameter of stem larger obviously could they help relieve this issue?

Even if (stock) valve guide life is reduced to say 50,000mi, that'd still be alright. I bet this will work without a hitch. Dig up some 2.2 roller tip rockers and valve guide life becomes a non issue.

Fantastic Upgrade Info! Thank You Brother!

I think your meth is wrong

I think your meth is wrong

Very nice bro

Really shouldn't be using 15 degree head rockers on a 23 degree head.

You don't think the rocker will slip off the valve left or right since the pedistools are not all attached to each other after cutting them, the only holding them from spinning is one bolt. I think that's what rocker stands are usually one piece

This is my kind of engineering! I love doing stuff like this. Those aluminum heads look familiar. What are they?

2024 just started and this guy is gonna win the worst idea of the year award. Just buy some roller rockers people that are actually intended for your application.

I see you're using my patented duct tape band-aid. Fun video, keep up the good work.

This is cool, if I ever build an SBC I'm going to try this out!

That's very creative

Jesel or Crower are cheap…. Why not just go with them?

why would you bother they still need trunnion upgrade why not just get roller rockers

Don't see the point but I love it make it work!

This is all wrong, the amount of movement on the valve tip will kill guides quick, LS and sbc rocker pivot lengths are significantly different, don’t cheap out; buy quality roller rockers otherwise you’re just kicking the can further down the road
