my arp head bolt instructions said 65 w/ iron 60 w/ aluminum due to expansion i went 62.5 just for a little piece of mind

 

80 ft/lbs for iron heads with 30W oil. 70 ft/lbs for iron with moly lube. 65 ft/lbs for aluminum heads. This is the torque for the nut. The stud is to be istalled finger tight. Straight out of the instructions.

 

Using motor oil over moly lube you will always have a higher torque rating. I would buy the ARP assembly lube/sealer it has sealer and lube in one tube. Its seems to be the alot like the teflon stuff you are reffering to. Same pastey texture and such. Very messy stuff. I use a liquid teflon paste as a replacement for teflon tape at work to seal Autoclaves and different plumbing.

 

That's wierd. I got the ARP sealer and their assembly lube, and it was 2 different tubes of different stuff in each tube.

 

Yea, its different. What pisses me off is that they leave the choise of what to use to the user. They need to include a tube of each in these kits.

 

I know I'm with ya...but I verified with ARP twice. I specifically said with Aluminum heads they said 80 ft/lbs. Take it for what its worth.

 

If you ask me the arp guys are idiots for selling these stud kits without thread sealant and moly lube, and letting customers learn the hard way. I just drove all around looking for moly lube, and found nothing. I found the permatex 2 sealant though. Is that supposed to be black?

 

with my head BOLT kit there was no molly lube. I would assume then that they want you to use just sealant? Why does this have to be so friggin hard? Does the sealant affect the torque reading? If you use molly lube and sealant, wouldnt the lube prevent the sealant from sticking to the bolt and the hole? WTF?!?!

 

You potentially could use either/or in the threaded holes, not both at the same time. They tried to make the torque the same for either by adjusting the formula. The trouble is that, if you use sealer in the block, you need something different than sealer under the washers and bolt heads or stud nuts. For our engines, if you use the bolts or studs, you need the sealer with teflon in the block threads to keep the coolant sealed up and some moly under the heads or nuts & washers to cut friction and get accurate torque.

 

ok cool! I didn't know that, and now I do! Thanks!
Ill just seal the threads, any squirt some molly under the head of my arp bolts.

 

I just used ultra copper rtv and stock head bolts. good to 400rwhp w/ the mr. gasket .026 head gaskets.
