Well one guy definitely missed it lol.
To the op imo if you are on a budget then I would put it together basically stock with a cam, tune it, and hit with a 100 shot and not worry. If you are building something with more money than I would put some into the heads and some good forged pistons and still hit with a 100ish shot. One thing the "nitrous purging guru" (I just couldn't resist lol) left out is when nitrous company's are saying it's safe to hit stock pistons with a 150 shot they are talking about a stock engine with low hp levels. Build the engine to higher hp levels and now you are asking cast pistons (and any other stock components) to handle 550 plus hp and you better be sharp on the tune, keep the rpms in check and have a plan B.
