[Kouki]

Just read the fucking instructions from ARP.

^someone having a bad day?

Check FSM
There's no TQ rating that differs because of the mods you have on your car.
TQ too much, risk stripping out your block.
TQ too little, lift.

TQ down to what the FSM states.
It's probably better to look at the ARP instructions like Kouki said.

It also depends on what you use for the lube on the studs. There is differant on wether you use ARP moly lube or just a regular "engine oil"

I would go buy the instructions that came with the studs.

90 -100lbs and re torque after first heat cycle

[HalveBlue]

The ARP head studs come with instructions that show you what the torque ratings are.

They ARE different from the torque ratings for the OEM bolts. The FSM instructions relate to the OEM bolts only.

I'll check tomorrow what the ARP instructions say.

im using the arp moly lube....
arp instructins says torque it to 65....
i dnt think its enough for that much boots...hence the reason i asked the question
ive heard ppl torquing it att 85 90 and was wondering if i should go that way

Ya, Enthalpy says 80lbs so that's what I'm gonna go with. People say to go in stages. I'll go 20-40-60-80.

This might help.

As per ARP instructions:

70 ft/lbs if using the ARP molly lube. 85 ft/lbs if using motor oil.

Aluminum heads should be torqued down to 65 ft/lbs because of their heat expansion properties.

Thats how I did mine two years ago - no problems! 100 Ft-lb seems like way to much. Pulling threads out of the head isn't fun.

[motegineon]

80lb with their sexy time lube

[slider2828]

80 as well...........
