Default LS1 w/Vindicator cam - Reliefs needed?

Building up my stock stroke LS1 and am looking to order some Diamond pistons to go with my gathered parts for the build.

Heads are Patriot LS6, 2013s and I will be installing a Vindicator cam with the stock rockers. Head gaskets Cometic 0.040". Stock bottom end.

My concern is head to valve clearance, for ordering my pistons. Can I get away with a flat top without reliefs, or will I need 2cc's or more? Anyone running this setup?

I will be checking everything upon assembly, but would like not to have to fly cut pistons later.

I agree might as well get the reliefs now and not worry about it hitting.
