Trying to chase down a tick / tap that sounds like it's coming from the valve train. Pulled a valve cover to look quick and noticed the rockers have a bit of play, mainly side-to-side as shown in this guys video:

Motor is a 355 LT1, CC503, stock intake/heads, LS7 lifters, CC hardened pushrods, GMPP guide plates, 1.6 ultra pro rr's, crane dbl springs, stock VC's.
Motor runs great, makes good oil pressure cold and around 30psi hot on the gauge. Gonna poke around more with a stethoscope after work with covers off.
Is there supposed to be any play? Or did these rockers come loose? Originally set them with motor out of car, didn't touch after that (~600mi on the build). I saw LTb1ow had a similar issue, less lash helped ?
Any insight is appreciated
