Novaman,
I had the same thing happen on my 283. I pulled the intake (reused the old gaskets, applied a 1/4 bead of RTV, let it set for two hours and torqued the intake. No more leak.
In response to your leak on the distributor. I originally forgot about the gasket and never lost oil from this area, after about two weeks of running I saw the gasket sitting on my workbench.

Good luck,
Kevin
