Exhaust manifold stud size please!

[thewraith]

So one of the studs sheared off and is flush w/the block. I want to helicoil and replace that smaller diameter stud w/one of the larger ones that comes in the kit. Can anyone tell me the sizes of the studs? There are 6 smaller ones and 2 larger diameter ones. I need the size of the larger ones.

thanks!

If I recall correctly the smaller are 8mm and the larger are 10mm. Unless the threads in the head are damaged you don't need a helicoil. Just remove the broken one and replace all of the exhaust studs.

The ones that aren't broken yet stand a good chance of breaking during install.
