Anyone know offhand what the lash #'s are for an early '90's 300 EM7 4 valve? I have the valve covers off of a friend's truck to look for problems with the Jake and I figured I'd better set the valves first but none of my books cover past the 2 valves. It has a 2 stage Jake (not a Dynatard) but the only way to tell that it is working is to roll down the window and listen. I drove the truck years ago and it seemed like it worked ok then, so something must have come out of adjustment since then. Any ideas?
