May have screwed up installing new cam. Need help!

That brings up another question I have. This is a hydraulic cam thats going in place of the solid cam. I've heard im supposed to adjust the rockers to 0 lash. Am I supposed to turn the engine to adjust the rockers? As in, start from #1, adjust that rocker, then rotate the crank a certain number of degrees, adjust #8, and so forth? Or am I supposed to adjust all of them at once without turning the engine. I know I'm supposed to limit the amount of times the engine turns to keep the cam lube on. I'd hate to turn it too many times.
Not zero lash...you are just preloading the hydraulic lifter. Yes its done when the cam is on the base circle so you are turning the engine just like when you are doing valve lash.
