Cheapskate Plenum Gasket fix?

My plenum gasket it blown. I'd like to fix it, but currently, the Hughes plate that fixes the problem permanently is out of the budget. Since I won't be driving this car more than a few thousand miles a year, I'm thinking I can get away with just replacing the gasket.

Is there an improved design gasket that works with the factory sheetmetal plenum? Should I use RTV on the gasket? I think I read somewhere that the factory bolts are too long, so I should make sure they don't bottom before they clamp. Any other tips?
