I didn't replace any I just took them out & clean them & filled them with oil then put them back in & started it & was barely wanting to run like it had no compression but finally fired and stayed running but was really rough I dont know if that was due to the rockers but I never moved the position on the crank the entire time

Adjustment for rockers is 14 ft lbs +30 degrees. Hopefully you put the lifters back in the order they were removed and pushrods in right place.

Everything was in its right spot I just need to know if I have to turn the engine & adjust lash after pulling & putting in hydraulic. Roller lifters because I took it apart again & 1 rocker was loose & another was almost loose all the way.

If they are in the correct locations the only adjustment is to torque them down correctly. If one is suddenly loose I would suspect it has a failed valve or dirt/lint that is blocking the oil from entering.
What was the original reason for removal? Valve train noise?
