Hydr lifters, adjustable roller rocker arms, had some noise, tried to adjust preload did i mess up?

Yup. Could be entirely normal. Those XE cams have some pretty fast lobes and that beats on the valve train and makes noise. That's why for a street car, I never, ever recommend a fast rate cam. All else being equal, you're not going to see a 20HP difference between a fast lift and good old fashioned slow ramp cam. But you'll sure as hell save a lot of wear and tear on the valve train and make less noise with an old school grind.

"ALL THAT" said, I never use that valve adjustment method. Never have and never will. I adjust them one at a time, right down the line. Get each one closed all the way on the base circle of the cam and adjust it. Then move to the next. Takes a little longer, but it works for ME.
