Thanks Dave,
I will try to find them at my local hardware store,
I too don't like the idea of using two gaskets.
@ Rodger: thanks for pointing me to NAPA for the
studs and Aauto if I need a new manifold

manifold studs...
The use of two gaskets, would only insure manifold warping or
cracking, and double the possibility for leaks.If you drill, use Cobalt
drills.Ya'll have a nice day, Dave.
