Rebuild engine that has problems with acceleration?

Having to raise idle with high lift cam in normal. Depending on how much cylinders were bored out did they install new pistons. Possible rings haven't seated yet and giving you blue haze, Either timing not set properly or whether cam to crank timing off or didn't grind cam correctly. Surprised you didn't buy a cam kit which would come with right lift and also lifters, valves etc.Seeing all that changes with camshaft change. oil press ok if idles at 10lbs and goes up to 30 plus accelerating. also possible valves opening too much. I believe I've talked to you before.
