The compression bump wont be a big problem to the stock tune. Like OLDH2 stated, if you buy the pistons i listed, check the box to add a ring set to your cart.
If you just want rings, go to the local parts store and get ring set for the pistons year and make. Like if you scored a set of mach1 pistons, buy rings for that year mach1. Same goes for 5.4l pistons, buy rings for that year.
Youll be paying attention to the rings thickness, mostly the top ring. 1.2mm or 1.5mm thickness is considered the normal. Most 01-up 4v got the 1.2mm, but this is not set in stone.
