Hi everyone-
In my house, I am renovating an under- central stair pantry area. The block in the photos is just below grade. Vapor barrier is non-functional plastic sheeting that I’ve cut back to the edge of the right wall. Previous construction was 1/4” plywood over 2×4 laid flat on the block. There were hot and cold water lines about halfway up the block, and a 30 year old nail strike in the hot line caused significant rot. Water lines were re-routed away from the area about 15 years ago, and the remaining framing appears to now be historically dry. I have removed all of the rotted timbers with one exception – the inside board of the doubleheader supporting the staircase landing/ceiling adjacent to the block. See A and B in the photos.
So.. do I replace that header? Or just continue with new work?
And, do I paint the block with Dry-Lok or similar? I will be installing new framing, paneling, tile flooring, and tin plate on the ceiling, but no heat, and continuing its use as a pantry. Air circulation is somewhat limited.
Many thanks for your input.

I can't tell from your photo if that's rot or just mold. Is the wood soft? Can you push a screwdriver into it? If so how deeply?
My wild guess is that you are probably okay with whats there but Im not there to inspect the construction.
Look up building science there are many good ways to finish a basement space but I wouldnt recommend wood paneling unless its very dry down there.
Invest in a dehumidifier too.
