AFR heads and header bolt help

[SMOKEDYA]

On my AFR heads the dam header bolts loosened off and fell out on 1 port.This happened all of a sudden,so should i run lock washers,or blue or red locktite?I use allen head bolts so they are easier to get to the head of the bolt.peace

I used locktite on my shortys, but I'm not sure if the rules change when dealing with aluminum. I'm curious too.

Whoever had my car before me hand tightened all the header bolts and they all loosened= exhaust leak from hell

I have been told that once you've got the headers on and driven it a while your supposed to go back and torque them down again.

i have heard that to about retourqeing them. But i've only put like 50-75 miles on it,so i didnt think they would come loose that soon?I've heard the same also about locktite and alum heads it's a peace

just check the tightness of them from time to time

Sometimes after a gasket change they will loosen up after a warm up. Percy's makes a nice set of header bolts that lock them in.

When you install headers you tighten the up. Then you get the motor hot and retorque them when it's hot. Then you retorque them again after about 40 or 50 miles while hot.

I will never ever install a set of headers again and not using these.

Some may think its expensive but they work! And can be reused infinitely..

Life is too short to deal with leaking headers.

I've had luck with using lock washers, in the past. I've also had luck without them though, but I do like the added security they provide, so hopefully I'm not stuck changing header gaskets anytime soon, being that it's a huge PITA.
