Tech Tip: When checking for valve spring coil bind, also check for retainer to valve guide clearance. There should be a minimum of .150? clearance between the guide (or valve seal if used) and the retainer.

Tech Tip: Flat tappet cams (hyd. or solid lifter) require to be broken in for the first 30 minutes of operation at 2000 rpm. During this time do not let the engine idle. If adjustments are required during this break-in period, you must shut the engine down completely. If using a spring with over 130 lbs. seat (or over 330 open), you should remove the inner spring during break-in.
