I've used GM EOS on every rebuild I've done except one and I wiped a lobe on that motor. Another additive that has been mentioned is Valvoline Synpower Oil Treatment. I've never used it, but it is said to have moly, boron, calcium, magnesium, phosphorus and zinc added to it. Sounds like a good multi-vitamin doesn't it. | I've used GM EOS on every rebuild I've done except one and I wiped a lobe on that motor.

4. Assemble your heads with old, used --STOCK-- springs. DO NOT ASSEMBLE WITH THE SPRINGS YOU WILL EVENTUALLY RUN. I keep an old set on the shelf just for running in a new motor, then change them out at the 30 mile mark. Manley makes a lever-type tool for this procedure, to be used with shop air to keep the valve seated. Don't have shop air?? Change them out at a buddies house or have the machine shop do it. What's that you say, you don't want the hassle of changing out the springs?? O.K., suffer the alternative then. | 4. Assemble your heads with old, used --STOCK-- springs.

The other way is a set of reduced-ratio rocker arms for break-in. I've heard that Crower Cams makes some 1.2:1 for SBC and 1.5:1 for BBC, but am unable to find them in Crower's catalog. I suspect they would be high-buck roller units though, something that might be out of the reach of the home builder who only does one or two builds a year. Somebody need to step up and make some stamped steel rockers in a reduced ratio that would be affordable for everyone. | The other way is a set of reduced-ratio rocker arms for break-in.

| − | 8. Make sure the motor is timed and use a known good carb or other induction system as well as ignition system. THE NEW CAM AND LIFTERS WILL NOT TOLERATE ANY GRINDING ON THE STARTER TO GET THE MOTOR FIRED. THEY ARE LUBED BY SPLASH OFF THE CRANK AT HIGHER ENGINE SPEEDS. HAVE EVERYTHING READY TO GO INCLUDING HAVING THE CARB PRIMED WITH FUEL. | + | 8. Make sure the motor is timed and use a known good carb or other induction system as well as ignition system.
