I've seen that JE is offering 1.000" compression height pistons and there are a lot of 6.125" rods on the market. Does anybody have this combo or have some pros or cons about it?
I know that even with 1.125" CH piston pin gets into oil ring land, so what's with 1.000 CH?

6.125 would be max. rod length in 383 with 9.000" deck height so I'm just wondering.

With my Dart SHP block I left the deck at 9.025" and was able to use the Mahle pistons and 6.125" rod with my new motor. The piston pin was not in the oil ring with this set up and the piston was .002" above the deck.

I used a .038" head gasket to get .036" quench. With a "zero" deck you have to use what you are talking about if you don't want the piston pin in the oil ring or a shorter rod.

There is nothing wrong with doing it the way 89 Trans Am did his, but you can do the more common 383 with a 9.00 deck 6.00 rod length, and a compression height of 1.125. They both have their pluses and minuses, the longer rod has better geometry, but the shorter 6.00 rod gives you more flexibility with ring height since the piston pin is quite a bit lower. And both are still a big improvment over the factory 3.75" stroke 400 sbc that had a 5.565" rod... if I remember right. I have never used those old short rods in anything I have ever built.
