ARP studs, Where did you get yours

[3400-95-Modified]

So yeah, I need the ARP individual pieces to make up the aluminum head kit since they only have an iron head kit...

Where did you get yours??

I need these part numbers.
8 - Undercut "Long" studs (11mm x 1.5 & 7/16" - 20) - ATP5.4LU
8 - Undercut "Short" studs (11mm x 1.5 & 7/16" - 20) - ATP4.650LU
16 - Hex Nuts (7/16" - 20) - APN58 or 12 point nuts (7/16" - 20) - APN12-1
16 - Washers (7/16" ID 13/16 OD) - APW1316N

I found 3 on CV products (recommended by ARP as a supplier of their individual parts), need to call for pricing on one, and I can't find the ATP4.650LU anywhere... only the ATP4.65L shows up and I don't know if its a bad idea to mix undercut with non undercut bolts.

I should probably piece together some kits...

That would be great if you could. I'm ready to buy my arp head studs.

Sorry I have to ask but, how do these work exactly ?

[3400-95-Modified]

Thread into head, put on head gasket, slide head on to studs, and put washer and nut on top... it promotes more even pressure when torqued, and also allows you to reuse them if the heads need to come off.

Oh that's great! thanks a lot!

[SappySE107]

Yup, no more torque to yield. I should have pricing tomorrow. I am going to order a set and check out the install for gen 4 heads. I have heard that a stud needs to be ground down to clear a rocker arm (seen the pics). That was gen 3.

[3400-95-Modified]

gen 4 is that 3500?? because from the looks if it it would be exactly the same.

Other question is would you follow the same torque specs when doing these?

And if they fit good order me a set... I haven't received a responce from anyone yet from CV Products.

[SappySE107]

It should be the same setup on the 3500 as the 3400 and 3.1 gen 2. I am not sure on the torque specs right now but that will certainly be addressed

Ben put me down for a 3400/3500 set. I need them asap. I was planning on pulling my engine apart for fun over the holidays.

I asked first you will come after me

[blackbombshell95]

Put me down for a 3400 set.

How come I always get your sloppy seconds? I wanna come first! Im still waiting for that IAC port measurement BTW.

[3400-95-Modified]

Oh I thought I saw an answer to that question on this board, thats why I didn't look it up.

Back in the 3500 manifold installed post... you asked and Ben answered. I'll check tonight if you still need to know, I'm pulling the crank pistons and cam out of the 3500 block for someone.

I bought some for the plenums I sell. 1/4" NPT pipe thread tap and then you can get a vacuum barbed nipple for it.

Oh yeah Ben... Any info on that bronze oil pump drive gear?
