after reinstalling the riser plugs i have a steady drip for the port side...any suggestions on getting it to stop. bought a new plug and it threaded right in with no issue. leaked. tried some teflon tape..leaked. thinking of silicone on the threads unless someone has a better solution..thanks!!

Pipe dope? I would think silicone would work, anything you put on would make removal difficult.

is the new plug tapered or straight thread?

Every manifold plug I've ever had has been a tapered pipe thread.

I use a tapered bushing with pipe tape. Then insert the smaller plug in the bushing. This saves the threads on the manifold.

It may - but it also means that you create an area for moisture to sit, the bottom threads in most of those plugs sit pretty low in the manifold, so the thickness of the bushing is going to restrict drainage in the bottom.

I think Chrisowold should double check he has the right plugs, as if they are not tapered they will probably thread OK but not seal and they'll bottom out instead of going tight.

Just don't over tighten whatever you do. :( Made that mistake recently. BTW, my threads were pretty gunked up with carbon, rust, corrosion, etc. Maybe you need to chase your threads to clean them up and get a better seal.
