Editing Valve train points to check

'''Here's a list of some areas of the valve train that need to be checked and verified. This is a general guide, and is not all-inclusive. Not all points will apply to all engine builds. There is no substitute for physically measuring critical areas like piston-to-valve clearances or valve spring installed height and coil bind. For those measurements, do not rely solely on published figures:'''

*Spring installed height
*Coil bind
*Retainer to seal/valve guide boss at full lift
*Retainer to rocker
*Trunnion to stud boss
*Piston-to-valve clearance (both before and after TDC on overlap)
*Push rod to guide slot in head (if used)
*Can use EITHER self-aligning rockers OR pushrod guide slots in head OR guide plates, not two or more of these at the same time
*”Rails” of self aligning rockers (if used) to retainer
*Rocker to valve tip (by adjusting guide plates if used)
*Rocker slot to stud (if using stamped rockers w/pivot balls)
*Proper geometry (push rod length)
*Rocker/polyloc to valve cover or baffle
*Camshaft endplay
*Distributor shaft and gear endplay
*Distributor gear material compatible with cam material
*Hydraulic lifter preload or solid lifter lash setting
*Timing set phasing
*Cam gear to crank gear alignment
*Cam gear end play if roller cam
*If using the SBC OEM roller lifters and retainers (aka dogbones), '''lobe lift''' must be kept below 0.354” so the lifters don’t lose contact w/the retainers
*Cam lobe to connecting rod on strokers
