Head bolts for 79 Omega 3.8

Hi all new to forum but was happy finding a forum for the classic oldsmobiles not many around. I recently picked up a 79 Omega 2dr base coupe with the 231 (3.8) V6 and TH350 trans. Car is not in to bad of shape 85k original miles needs body work but goes down the road like a champ aside from a misfire issue that after the routine tune up was done vac advance etc was all checked went and did a compression test and found all but one cylinder are around 140-142 psi and the odd one out is at 90psi. After one of my more computer savvy friends put a seriously small camera in the plug hole we found it has a burnt valve gaskets and valves are easy to get but I cannot for the life of me find head bolts at all found a head stud kit for a 84 regal 3.8 but not much on interchange. I have been told just reuse the bolts and I have in the past with a 72 cutlass I had when young and dumb and never had an issue but thought I would see what those a bit more experienced than myself might think or know possibly where to get the ever elusive bolts lol. My dad has been scratching his head for about a week trying to for certain think of what other year, make etc is a for sure match but think his 5 year retirement and not having worked on older vehicles much since the early 2000's has caught up (after turning wrenches for 42 years can't expect him to remember everything despite working at an olds dealer for 15 years I thought he would pop off with it instantly lol) Any info is much appreciated

Welcome to the group... Unless you can see physical damage to the bolt/threads, reuse the original bolts...

Head bolt torque is 80 FT/LBS and Intake is 45 FT/LBS... Sequence is shown in photos below... If you are interested in purchasing a 1979 Chassis Service Manual, I may have a spare in storage... Where are you located??

Unless one shows a specific problem, re-use the head bolts. Consider replacing the timing chain, both gears and the oil pump (kit) if it has around 100K on it.

Good luck!!!

Awesome thanks so much. I found a manual on ebay but not sure if it's a full shop manual or basic deal that doesn't go into specifics. I'm in upstate NY near the Canadian border to montreal. And Sugar Bear have new chain and gears on order new oil pump and cam and lifters as well if I have to getinto the motor decided I'm going to make sure all is good and up to par never been one to do one major thing then have something I knew I should have changed give out after and take the motor out lol bit more of a project than planned but car is worth it.
