Need help with stopping a Vacume LEak

I start my quest today to find a washer that won't bend. My 4.2., 4.0 head, MPI engine has not slowed down in 600 miles. I have a vacume leak and I figure that it is comming from the intake manifold. The wahsers I had used to hold the intake and exaust manifolds on have deflected and cupped with the torque of the bolts. My guess is that this is part of the problem

Questions:
???Is it OK to use a hi temp rtv or other sealant on the manifold gasket???
also, Where the heck do you find 3/15" or 14" washers. I'm planning to visit some specialty hardware stores this morning, but plan on visiting some of the local welding shops to pick up some scrap 1/4" to make my own if I can't find anything. I checked all of the big names, Home Depot, Lowes in town and found nothing, but that wasn't a suprise.

Thanks in advance.

Re: Need help with stopping a Vacume LEak

I'm not sure about the 6's but my 304 doesn't have any washers on the intake bolts. My intake manifold uses a metal gasket and I used LOTS of rtv on it. Edelbrock actually suggests using rtv instead of the rubber seals they provide. Don't know if this helps but, good luck.

Re: Need help with stopping a Vacume LEak

I believe you are suppose to use the cupped washers on the exhaust /intake bolts.I am sure a dealer would be happy to lighten your cash flow in exchange for a few .or a junk yard with any AMC sixes would have some.
I know everyone recommends NOT using the intake /exhaust gaskets ,but I had to to stop a hellatious intake leak .Gotta do what you gotta do.
