Re: Exhaust stud
Be very careful when you drill for the helicoil insert. You are close to the exhaust port and there is a danger you run into it with the drill. Do you have the head off the motor?Petrosexual wrote: Mon Jan 30, 2023 11:44 pm Yes, oddly enough I know about those......pretty useless for me as THEY DONT STATE THE THREAD SIZE....which is what I need in order to helicoil the head!

Re: Exhaust stud
Here is a little tip: I used two exhaust flanges with the ribs machined off, mounted on top of each other on the exhaust port. Then using the empty hole as a guide for the drill. This makes sure you have the correct alignment. It is also good to mark the depth of the hole and mark the drill accordingly, so you know when you are in far enough.

Re: Exhaust stud
It is worth checking to see if the old exhaust copper crush gaskets are still in the head. When I changed my exhaust over I noticed there were two old gaskets in the exhaust port hence that would push the collar our further possibly meaning the stud appears to be short of length. Just a thought.
