EGR ports on exhaust manifold

Does anyone know off the top of their head what size caps I need to buy to block off the egr stuff on the exhaust manifold?

no i just had mine welded up

I actually cut the old ones off and welded them shut but I got some slag stuck on some of the threads on 2 so i was just gonna go buy 4 matching ones.
