So I decided on running a standard 460 piston with one base gasket. With that in mind I splurged and bought the highest quality piston I could and got a Meteor brand piston.
The quality difference compared to the others is tangible and visible. It's also .02mm taller than the Hyway pop up piston, which means my squish gap should be .96mm, and a compression ratio of 10.5:1. I am quite happy with that.
I took my rather pricey piston and then proceeded to ruin it and put two windows in it lol. Not too bad considering the old beat up lathe I had to work with.
Now I just need to finish cleaning up the ports and get if running.
