340 stroker build questions

So I'm putting a 4 inch crank in my 340. Block has been tanked and measured. Needs to bored .020. I have a forged MP crank, Wiseco forged pistons and K1 h beam rods. What else should I do to the block for prep? Should I spend the money and get the Hughes stud girdle kit for the mains? What should I be more concerned with a windage tray or the girdle? Can I do both? My goal is to have a durable 425 horse street car. Possibly add a turbo down the road. Probably will never happen but I want to build the bottom end to handle what ever. Only doing it once. I would like to use the Milodon road race pan,pick up and windage tray but not sure if it will work with the girdle?
