Block is going to be dropped off at engine shop tomorrow. I have weisco 3.800 Pistons im getting bored to match, the Company suggests you use plasma Molly rings but I have seen on a forum that they do not work well when the rings expand from the turbo/heat. also wanted to know how much ring gap will need to be put in the rings because they will expand right?

Sub'd, as I'll be building a 5.3 in a few months for a turbo truck! Running the same Pistons as well!

Never gapped the rings from what I have researched many people run these ranges (I was planning to go turbo this year but wont for a while):

top ring .026-.028
second ring .028-.030

Then again many people run stock and kick *** without issues such as Denmah lol.

But I have seen a lot of ppl saying the plasma Molly rings getting brittle from the heat

This is what wiseco sends with their piston sets. It is just a reference and each builder may have their own style/ way of setting up the build.
