ARP: studs or bolts

[mytight95]

Well i am getting everything together to put my heads on next weekend. I have a set of ARP head bolts they have been used twice so far..... would it hurt to reuse them or do I need new ones....

What would any major advantages be to using studs on the car? It was suggested in my other threads to use Anti-seize on the washers to the heads, would the ARP moly-lube serve the same purpose or no?


Think ihave got this pretty much nailed down, i know i am being a pain, but i don't want to mess up it took me around 6 months to stick back enough money to buy them.


thanks guys

head bolts are torque to yeild, you can only use them one time. get new bolts. i used thread sealer on mine. the new washers come lubricated.

Not the ARP's

You can reuse the ARPs with no problem. Use the ARP moly lube on the long bolts and ARP thread sealer on the short ones. Torque them all to 65 lb-ft.

AFR's site says....70 lb ft on the lowers and 80 lb ft on the uppers... I was mainly trying to make sure i would be ok reusing them for the third time.........still may go with studs undecided...

That spread they give assumes you are using their recommended lube/sealant on the top and bottom. I used threadlock on the tops and seal on the bottoms then torque the tops to 75 ft-lb and bottoms to 70 ft-lbs.

I still don't get the point of the studs other than ease of alignment on installation. I say save $40 and use the bolts. And yes you can re-use the ARP bolts. ARP says no more than 3 times, but if they don't yield at max torque, then in theory you can use them all you want.

i bought arp assembly lube to use on the threads, and plan to use anti-seize on the washers. i also bought the arp thread sealer to use onthe one in the lower bolts. I also plan to use anti-seize, on all the header, intake, and bracketry bolts.....

am i missing anything????????

Do you still generally use anti-seize on the rocker arm bolts.....or would you use some kind of threadlocker(thought this might pull the threads with it if ever uninstalled)

70 and 80 is with 30 wt motor oil. 65 lb ft with the lube/sealer is equal to 80 lb ft with 30 wt oil. The sealer/lube is much slicker than oil.

You follow what the bolt manufacturer states for torque specs NOT what the head manufacturer says. ARP calls for 60 ft/lbs on ALL bolts for aluminum heads using their lubrication.

i vote studs. Although you have to pull the studs to clean the surface when it blows, they have allen heads, But, when you go to put the whole thing back togther, the studs hold the gasket all nice, and the head just slides down the studs nice and even. i like em.

I was thinking you could tighten studs a bit more than bolts thus getting more clamping force.

so would that be 60 lb-ft on the top bolts as well as the bottom ones? The thread sealer isn't as slick as the lube is it......? So should i use the arp assembly lube on the washers or the antiseize.......
