Grand Am camshaft- Is notching pistons required on all install

With the GMPP Grand Am cup camshaft, is it essential to notch pistons on every install, eg. can you install on different centreline and get away without notching?

With stock heads.

What is the centerline on that cam? I don't think that you would need to on un-modified heads. I think that if we are talking about the same cam it is on .570/.570 on a 106°?
