i recently took off my header to change the gasket, and once i put it back on. 2 of the bolts went in, but wouldn't tighten, so i pulled it back out and noticed that it actually stripped out the threading from the cylinder head. so now, the bolt just goes in and out. is there a way to fix it???

it's #6 in the image

 

You are more than likely going to have to re-thread the head with a slightly larger size, and then you can use a bolt with the same thread pitch to bolt into the head

 

I would try using a Heli-Coil inserts to repair it.

 

Get some ARP studs and epoxy the f*cker in there.

 

 

bump, just stripped another one when taking off my header

that's what I used. be sure to torque to spec when you reinstall the header.

 

where would i buy this heli-coil stuff?
