Does anyone happen to have a gm and/or offy part number for valve cover studs? I am looking to obtain some new studs, or even used studs and nuts. It appears that the stud sets offy used to have available are either temporarily discontinued (maybe just for the time they are spending to repair their valve cover casting). At any rate, it looks like I am going to have to have to sort out a grade for the studs and nuts, and then have some made up and the only example I have is on my running motor which I don’t want to remove.
I was wondering if ARP had something similar. I seem to recall that they were coarse threaded on the end that screwed into the head and replaced rocker shaft bolts and had fine threads on the end that protruded through the top of the valve cover. All this is from old memory though.
