My motor has 25-30k on it & I’ve never had the valvecovers off of it (actually as I type this I realize I did once when I had the intake powdercoated - never touched the rockers). Are they torque to a specific ft lbs? This is not normal on a Gen 1 style SBC. Most (almost all) chevy motors have lash-adjustable valvetrain (Mark V big blocks do not, but need converted when adding a higher lift cam). If you have to adjust the lash, you will have problems with them loosening again. Do yourself a favor & spend the few $$ on polylocks. --- _[View the full topic](https://forums.speedlife.net/t/orr89roczs-1989-camaro-iroc-z-5-7l/188547)._
