Hey Everyone

Ive got some ARP Head bolts i bought brand new.

Forgot to buy ARP moly lube, if i use some assembly lubricant under the bolt heads, will i have any issues?

Thanks!

It should have torque specs for 30 weight oil.

Yep it does, just if cam/assembly like would function the same way, id be a little more comfortable

On the arp molly grease pack it has a warning about useing other lubes could cause gasket failure so I would use oil or their grease to be safe.

make sure you clean the treads in the block so you get a proper torque reading.

good luck

Awesome, thanks guys!

Best way to clean threads is just to go buy a tap and run it through them?

Thanks!

FYI - I called their tech line and they do not recommend using engine oil for the head bolts. I agree because the engine oil seems to compress between the threads causing more resistance as the bolt is torqued higher to final spec. Save the headache and do it right the first time and just use the ARP moly lube for a more accurate torque reading.

I used oil before and what a disaster it was on my buddys gto his heads were leaking coolant everywhere....when i did my motor i forgot to get arp milly but i used engine assembly lube with graphite and havent had an issue with anything.

You can use oil SAE30 valvoline racing is good, but I reccomend 85ft. lbs for larger bolts(11mm), and 30ft. lbs for smaller bolts(8mm). You should always cycle an new set of bolts before you just torque them down and go.

Did you "cycle" the new set of bolts, and did you have a torqure wrench that was accurate?

After a heat cycle, re torque. Im not sure about the bolts but your supposed to with the studs.

I would guess he means to tourqe them all the loosen and re tq them.

kinda like the arp rod bolts they say to tq them 3 times. I am sure it helps the threads kind of seat to each other and give a better tq reading.

this is only for reusable bolts do not do this with a tq to yeild fastener

yep a tap works good. just make sure you get all the crap out of the whole especially coolant. for that you can use some compressed air.

Got them all clean, i just gotta run the tap through.

Im 99.9% sure my bolts are re usable, they better be atleast, thats why i paid $120 for them!

Think ill just get the right lube for them, then ill torque them a few times.

Its not bad for the head gasket to torque them then loosen them 3 times?

i never actually seen anybody torque them down and loosen them on an ls1 engine. you just torque them down in 3 stages for the arp studs 30lbft 50lbft 70lbft (just the 15mm ones)

5 smaller ARP bolts and torque them to 22lbft.
