Cam break-in Questions.... On an engine run stand

I am building a 512 stroker that will ultimately have a Holley EFI, Hyperspark ignition etc.

I would like to do a break in of the cam on an engine run stand. If I did that I could run on a carb with the regular fuel pump and distributor that was in the motor originally. This way I would not have to somehow rig up the in tank electric fuel pump as well. Also, I would like to do a break-in before putting on the ceramic coated headers so that I would not burn off the coating during break-in. Either I could get a pair of $99 headers or find an exhaust manifold at the boneyard.

My question is ...Am I making a big mistake by not doing the cam break-in with the final product? If so, why? What would you do differently? Open for suggestions
Won't make a bit of a difference.
