I recently installed headers and I definitely have a leak where they bolt to the heads. I used ARP Header bolts except for one OEM bolt on each side because the ARP wouldn't start to thread in properly in those holes. I applied ARP antisieze to all bolts and I've read on here that 17 ft lbs seems to be the torque spec everyone uses but I only torqued to 12.5 ish ft lbs to account for the antisieze and I'm scared to go much tighter. For those of you running ss bolts and antisieze what did you torque them to?

I didn’t use ARP, but did use the stage 8 locking bolts that came with my headers. Torqued them to 20 ft/lbs, and not a problem since install. (They are stainless and I used anti seize)

I used stage 8 locking bolts on speed engineering headers no leaks after 1 year no problem with install at all

Thanks guys. Torqued them down to 17 ft lbs cause it's as far as my torque wrench goes and no more leaks

Nice! 12.5 seemed low if I’m being honest so glad to hear a little more solved it.

Yeah it was definitely low but I didn't want to strip a head
