ARP stud install and engine tear down

[IDIBRONCO]

copper anti-seize.

I like that MUCH better than the silver crap that I find around here. They do the same job, but the silver stuff gets everywhere no matter what. The copper also seems to clean up easier.

I agree! Took me a decade to go through a $12 bottle and works on all high-heat fasteners to boot.

But to the OP, any anti-seize you already have works fine on injectors, no need to go buy copper.

Quick question... when I install injectors, do I need to put anything on threads?

They should be torqued to 35 ft lbs too.

Thank you, I was wondering about that

Finally got both heads on, will have them torqued tomorrow.

Make sure you use an OEM style stat.

Roger that. Also, why is it that head studs are only supposed to be threaded in hand tight? Should I not give them a twist with the allen key?

I would do whatever the install instructions say, never have used them myself. Looks like you removed the a/c outer housing to make it easier to pull the head?

I had that question too. I think the point is to make sure it has lots of meat of the threads, but to very much not bottom the stud out.

@IDIoit has had 2 or 3 blocks he built up crack on him and one thing he wondered was if the studs turned with the torque wrench and bottomed out under torque. I dont know anything beyond that but apparently its a very bad thing.

I don't think that was very much help, doh.

I have to confess, I gave my studs a twist with the allen key, but ever so lightly. I wanted to make sure the studs were in all the way. 5 years later it's still working.

I installed lower studs per ARP directions and this happened,
its only happened once (crosses fingers)
now I install with red Loctite, all the way down by hand, then back it off 1/2 a turn.
then let it sit overnight before assembling.

Thats correct. It sucks taking everything out but if you’re gonna do this job with the engine in the truck, plan on getting everything out of your way because you’re gonna need every inch of room.

Just wondering if they only go in hand tight and a Allen wrench can screw them in, why couldn't you put the heads on then the studs?
