I have adjusted the valve lash 5 times and it keeps going outta whack!
First I adjusted cold .022 int .024 exh drove it for about 5 miles....Sounded loose, so I adjusted same hot. Sounds/runs great! 10 miles later, running funny, lots of valvetrain noise....Adjust again, thinking maybe the damn thing wasn't warm enough the last time (slack in ALL), so I adjusted again. Runs great, sounds great, and go for a drive about another 10 miles or so, starting to run differently, more valvtrain noise.....Adjust again (slack in ALL), go for about 30-40 miles runs and drives great at least half the way, but by the time got home, running a little funny and valvetrain noise.....Adjust again tonight (slack in ALL). (Also, the lifters were all perfect before putting the new rockers and pushrods in.)
What the heck! Am I really losing my cam on all lobes or what? Something is really fishy, and the jam nuts are all tight when I go to adjust. I'm really confused and pissed!!!

oil pumps rockers, stands, spacers, and good ball/ball pushrods. SON OF A.....
By the way, I'm adjusting the valves by starting with #1 cyl, when the exh starts to open, adjust the intake (do the same for all cyl's) then back on #1 when the intake is almost closed, adjust the exhaust (do same for all cyls).
