I have a set of four std. bore 265 Chevy pistons and an 8 set of rings for my 2.0L build. My question is: Is it more practical to build with these parts, or with OGTS's 2.0L pistons? Will it be a cost wash with the extra machining required to use the Chevy parts as opposed to the ready to use Opel parts? I want to proceed, but could use a little advice.
