Well, my book says for adjustable rockers to tighten them until you can just barly spin the push rods, however I did this and some of the bolts are barely past finger tight. Turned them 1/4 turn more and they came off when I tested it at the lake today. I tightened them back down to torque and I get valve lash or a tapping sound when I get above 2000 RPM's I am very confused. I changed them from all torqued and got compression back in 2 cylinders, but now I can't get above 200 RPM's, before I made the change I could get to 3200... Any ideas would be great
