Did some more diging on my recently aquired WD to decide whether to fix it up or use it for parts. Manifold was held on by bolts instead of studs (one twisted off flush with the block...that will be fun) I noticed that three out of the six threaded holes in the block were blind holes and only about a half inch deep. Does that mean that someone has twisted the ends off some studs or they supposed to be that way. Seems like a half inch is pretty short for a stud thread. If it's normal, I'll just clean them up with a bottoming tap and proceed. If not, I guess I've got a lot of tedious work to do. What do you think...can I get away with using the half inch deep holes???

A couple of those stud holes are deep and wet and will need sealer on them.

The 1/2 in depth is dry and proper for the others. Originally the studs have a slightly oversize thread on about 5/8 in of the end that threads into the head, to lock and seal them.

I hunted all over for new studs(because the originals are almost allways shot for me). I could not find "studs" of that length, even through commercial bolt suppliers or industrial suppliers.

I ressorted to buying grade #5 3/8 bolts about an inch too long, hacksawed the heads off, and threaded the short end to go in the head. With adjustable dies you can even make the 'interference' threads to fit snugly in the head. IF you're a perfectionist you could use stainless steel bolts.

I find I have better service and luck with the small additional cost of using s/s nuts and washers, rather than brass. I've had problems with the brass nuts shrinking from the heat cycles and getting tighter than the hubs of h---. They didn't rust, but got about as tight.

And ofcorse, use 'Neversieze' type lube on the nuts.

I allways assume that I will have to work on everything again some time, so I try to make it easy for myself later. No short cuts or cheats that will bite me later.

I have had good results when using Hard bolts for the manifold..But I do use a liberal abount of anti-seeze on the threads.. You arent going to tighten those bolts all that tight anyway, or you will break the manifold..! I like to rub High-Temp sealer into those Asbestos gaskets to bind them together and stick them in place... Not sure about the hole depth..you sure don't want any open where a sleeve is behind it....!! I seem to remember that you get water from some of the holes... Guess it won't hurt if they are open, just seal the threads well and don't use too long of bolts..!!
