In my down time lately I've been reading alot about injectors for the VP44 24 valve. Trying to learn and read reviews check prices and the like.

 I have looked through DAP and some others. Some look kind of "shady" or maybe that isn't the term but for whatever reason I didn't trust what they were saying. One on the other hand one seems to make some sense, Dynamite Diesel. All I know about this company is what I saw and read on their site and reviews of their products. I was just wondering if anyone has used their injectors? I did notice however that their prices are nearly double compared to DAP so I'm also curious as to whether or not it's worth it.

 .I'm not trying to start anything here between companies by any means nor bash either company. Just wondering how or why the price of the injectors can vary so much.

I'll be in the market for injectors come this summer so thought I'd start doing some homework and came across this issue so thought I'd put it up here and ask others opinions.

 I'll most likely purchase from DAP when the time comes but my curiosity got me on this.

Dieselfuture, when I received mine, they did look like bolts. That's because they have the nut threaded to just cover the nut. I was happy when I opened them & seen that they were studs & not bolts. They also thread to the bottom, so there is a lot of stud in the head.

Like they say, looks are deceiving.

I'm looking for my pictures to see if I've gone 

New I wasn't that crazy, mine were bolts. Guess it's time to upgrade to studs, just kidding I think these will be fine. I can sleep now

Gone or going back for seconds? I had to look at the picture a couple times to see they were studs, sure looked like bolts at first.

I think I'm ok, they were bolts, you can see arp on top of them

What is the torque spec for the ARP bolts? 

I remember the last one for mine was 125 foot/pounds. Done in 3 steps up. It all explained in the instructions when you get the studs. DO NOT do a hot torque! Even stated in the manual from ARP.

ARP's are studs.

I honestly don't remember, I might have put them to factory torque spec. I went with longer bolts just for a piece of mind so I don't pull threads out.

Actually I have A1 head studs not arp, but yes what you circled is a stud. We're talking about rocker arm bolts.

That other bolt on the right is a apps mount

oo, lol.  yea some stuff arp makes is bolts.  "studs" get thrown around because of the head studs.   ARP makes a bunch of bolts and studs.

Why not do a hot torque?

Good way to break a stud. high chances of hot torque will make the studs fail... Again straight from ARP - DO NOT do a hot torque. Why would you want everything expanded and try to clamp the head tighter? Why not do it cold when everything is condensed and get a good clamp on the head as the engine warm up everything expands and tightens more.

There is a video on YouTube guy breaking will start hot torqueing arps on a cummins

Yup... I forgot about that and he did a good job of breaking that stud.

I swear autocorrect is messing with me, it changes things after I submit, I reread what I typed looks good then later it's all screwed up. Instead of ( will start ) it should have said ( a stud )

I haven't read the installation directions (yet). That makes sense. What's your opinion on using anti seize on head studs? Only asking because in refineries we use anti seize on mild  carbon steel studs on heat exchanger caps as well as piping flange connection bolts. Refineries require anti seize on the threads, both sides of the washers and both sides of the nut. This is to reduce the co efficient of friction in an effort to achieve the proper torque spec. 

 

I've always been taught to NEVER use anti seize on any engine component fasteners, except exhaust manifold fasteners. 

I tried to reply but it's not showing up. Idk what's going on.

The kit comes with the antiseize. All spelled out in the directions.

I'm sure they have their reason for putting anti on the side flapping in the breeze and I'd love to know what it is!

I never had a problem using anti-seize on certain fasteners in the motor. Internal components I generally use arp lube same with head studs or other studs. Exhaust things I use high temp anti-seize, has copper in it I believe. What's crazy to me is how much torque specs can change from using motor oil to arp  lube.

Didn't know we could do that, guess I never looked into it, didn't see the need to. I think @JAG1likes doing it just to mess with people
