Intake Gasket advice

The reason I ask is Ive been chasing down some oil burning....

So I pulled the plugs and the threads were wet and the insulators were sooty.....

At first I thought it was the aftermarket valve seals -,so I pulled the intake to look for staining on the valve stem.

Forget the staining...it was clear the intake gaskets had deteriorated and oil was migrating into the ports!!!

Time for some FelPros!!
