Helicoils. Find out what thread and pitch the stud is and then get a kit to fix it.

I put my exhaust header at like 45 pounds with helicoils. These things are great.

If ANYONE has their head out of the car, they should seriously consider doing this. It takes an hour and is ver yeasy to do.

It depends on if the heli coil kit is a different thread pitch and size.

DO NOT USE BOLTS

Use studs.

Aluminum head + steel bolts = fubbared threads after removing the bolts a couple times from the heat cycles and expansion.

Studs with a high heat thread locker.

while doing my HG on my 87 turbo, i had a head off of a 1990 NA supra milled and rebuilt but while taking the exhaust manifold off all of the studs came out perfectly cuz the nuts were rusted fast to them. Got new studs and nuts from toyota and had no problems since.

However, if your less fortunate and the stud does strip i strongly recommend anti-sieze when putting the nuts on a heli-coiled stud and high temp thread lock when putting the stud into the heli-coil.
