rocker arm

i rebuilt my 89 f150 302 it ran fine before i took it apart. when i put the motor back together all the rocker arms tighten down fine. just some are loose where they meet the push rod like as if they have worn down but they were fine before i took them off is then any order they should be out back on i see letters stamped on the rocker arms

the rockers and pushrods should always be put back on in the exact order they had been taken off.

in this case your best bet is to buy new pushrods and rocker arms. otherwise you will eat the cam. just curious, have you turned the motor over by hand to make sure its just not the position of the lifters that are making some more loose then others? so in other words if the loosness changes to different set of rockers as you rotate the crank then everything is probably fine.
Lets see what others say also.

the motor hasnt been started and run yet correct?

did you perform the 20min 2000rpm break in period on the cam before you drove it? was the cam properly lubed as well? if not you may have a bad cam lob.
