On low lift applications it may be necessary to shim the springs to 20 or 30 lbs over the recommended seat pressure to get the right open pressure. Failure to do this may result in valve float and engine damage. DO NOT USE Z-28 SPRINGS! They will have a very short life and not enough pressure. We recommend H-11 tool steel springs, which cost about $160.00 per set. They are cheaper in the long run, especially if they prevent an engine failure. Some of the stock diameter valve springs for .550-.600 lift will work but they will still have a shorter life than the H-11 version. Remember these are race profiles and have very radical valve motion.
Good spring maintenance is very critical. Cams with dwell at Max lift (HDML series) usually have about a 6500 rpm limit.
