want to bore a used engine out 30 thousandths, but cant find pistons to fit??

hey guys, im looking to either bore a used 4.0 SOHC out like 5 thousandths or 30 thousandths depending on what pistons i can find..i wanna put 350ish horse through the engine, so im looking around for forged pistons, but cant find anything...if i bore the engine 5 thousandths to clean out anything that has happened in the cylinder, do i use the stock bore? or do i need bigger?...and what about a 30 thou. bore? does anyone know exactly where i can find some of those pistons, i have looked and looked, and NOTHIGN!! ughh

thanks alot

They have some forged pistons, but they aren't cheap! You'd have to call them to find what bore sizes are available.
