Intake manifold vacuum cap

Intake manifold vacuum cap
There is a large vacuum port (maybe 1/2 inch) right above the header on 12a manifolds. Located next to the brake vac line and under the split air pipe block off. My problem is that I've had to replace the vacuum cap a few times on this port due to heat from the header rotting the rubber. Has anyone come up with an idea for this or does anyone else have this problem?
Maybe pull the nipple out, thread the hole and stick a bolt or plug in it?
