Im assuming you have ped. mout rr. Here's what to do, compliments of Chris:
Valve adjustment with new roller rockers 1) Install one rocker arm at a time by inserting the 5/16" bolt through the top of the rocker arm, MAKING SURE THAT THE FLAT SIDE OF THE FULCRUM IS FACING THE BOLT HEAD. After this is done, slide the pedestal onto the bolt with the curved area of the saddle contacting the rounded side of the fulcrum. Next, slide the guide channel onto the bolt with the raised edge facing up toward the rocker arm, then loosely thread the bolt into the head, while making sure that the pedestal is in the channel and the saddle is in the correct location on the fulcrum. Install all 16, and snug down the bolts by hand. 2) Rotate the engine until the balancer reads TDC on the compression stroke. 3) Check the rotor in the distributor, and verify that it is pointing at the #1 wire on the cap. If it's not, rotate the engine 360 degrees. 4) To find the point of zero lash, spin the pushrod between your thumb and forefinger while slowly tightening the bolt with a 1/4" drive ratchet. Tighten the following rockers until you feel the first bit of drag on the spinning pushrod: Cylinder #1 intake and exhaust, Cylinder #3 exhaust, Cylinder #4 intake, Cylinder #7 exhaust, Cylinder #8 intake. 5) Now torque each of those to 20 ft.lbs. 6) Rotate the engine 360 degrees, so the balancer reads TDC again. 7) With a 1/4" ratchet, tighten these rockers (again, to zero lash): Cylinder #3 intake, Cylinder #2 exhaust, Cylinder #7 intake, Cylinder #6 exhaust. 8) Now torque each of those to 20 ft.lbs. 9) Rotate the engine 90 degrees, and with the ratchet, tighten to zero lash on these rockers: Cylinder #2 intake Cylinder #4 exhaust Cylinder #5 intake and exhaust Cylinder #6 intake Cylinder #8 exhaust 10) Now torque each of those to 20 ft.lbs. ***If it takes more than a full turn to reach 20 ft.lbs. torque, after you have reached zero lash, you're gonna need shims. Thick shims represent approximately one turn.
