Step Studs, Stripped head Options

[BMXerror]

Anyone ever stripped the threads out of the head with the exhaust studs. Well, the guy who owned my car before me put studs that were too short in and they didn't bite on enough thread. He tried to tighten them with not enough thread and stripped the head out. To the point, does anybody make T4 step studs? If not, has anyone else encountered this problem (doubt I'm the only one), and if so, how did you fix it. I went to four places looking for step studs today with no luck, so any help would be great. Thanks.

I put in a helicoil, which has held up a couple years so far. I wouldn't call it easy. If the engine is in the car and you're lying on your back, it's cold out, and you haven't used a tap before, and aren't familiar the consistency of 914 head material (which is soft). Well, there is the danger of having the tap go in the wrong direction making it difficult to install your exhaust, or worse, having the tap merely drill a hole. good luck. the factory tapped farther into the head than is used by the stock studs, which is probably why you found "short" studs.
