This thread is a good reference for powdercoating best-practices.
It seems that there is no "easy solution" to removing powdercoating.

Ouch they should have masked the gasket surfaces. Again no easy solution as PC is hard. Get lots of dermal bits and sand paper and have at it.

I unfortunately agree.
I think the valve covers and side plenums are salvageable. You should sandpaper down the channels that hold the valve cover gaskets. Then, you apply HondaBond 4 to channels.
To my eyes, the coolant crossover, oil filler neck, and the air guide need to be replaced.
You didn't show pictures of the intake runners (pipe organs.) Are the mating surfaces powder coated as well?

A flapper disc on a 4" grinder and a light touch works great. Then for a final finish use a hard flat surface with varying grits of sand paper(7" DA discs seem to work best) and lap the parts in a figure 8 pattern to keep all the surfaces level. Had to do this quite a bit in the machine shop when it was a part I couldn't mount in the vice and clean up the surfaces with a shell mill.
Take your time and it will come out just fine. The parts look great BTW. Just getting ready to do a refresh on my 86 as well.

Or find someone with some B17 stripper and start all over again and have them masked correctly. Would still be cheaper than buying new parts... Although those would make nice wall art if nothing else.

B17 is the stripper they use to dip the parts to remove paint and powder coating. I have used it many times, it just takes a day or two to soak it and strip all the old material off. May be your best bet at this point. It's to bad since they turned out great.mim really surprised they didn't brush the powder off of the mating surfaces before they baked them... It only takes a few seconds to do.
