Is there a proper procedure for installing studs?
Thanks...Dave

Dave -

From what I can find out the center intake bolts are 2-5/8 inch long. If anyone knows any differently please chime in.

So you would probably be looking for 3 inch studs or possibly a 3-1/4 inch stud. ARPs site is hard to navigate for an exact bolt or stud but on Dorman's site I found these that look pretty close.

I found these on the McMaster web site. You can pretty much find any combination of length, fully threaded or partially threaded stud on it.

ARP would be the most likely to have a stud with allen head recess or a screw driver slot in the top. If you have a dremel it would be pretty easy to add a screw driver slot to the top. I would probably install them with some blue thread locker to secure it in the block.

Just based on my motor I can't see how positioning the fuel log slightly higher should create an issue. If the fuel log is hard piped to an OEM type canister filter the line fittings would need to be loosened to re-position it and then re-tightened.
