Following these recommendations will increase the service life of Manley valves and valve train products.
TECH TIP #1
Manley recommends silicon aluminum bronze guides for the race track and cast iron guides for street use. Manley chrome plated or nitride
finish stems work well with either guide material. For street applications Manley recommends .0015” - .002” intake valve to guide clearance and
.002” - .0025” exhaust valve to guide clearance. Manley’s viton oil seals should be installed on all street or race engines. The installation of these
seals will positively dry up the combustion chamber and reduce deposits on the back side of the intake valve. Because of their effective oil control,
when installing Manley oil seals valve guides should be sized to the high limit.
TECH TIP #2
Valve seat widths are very important as 75% of the heat of the valve is dissipated through seat contact. For street applications, Manley
recommends .060” minimum intake seat width and .070” minimum exhaust seat width. Remember, all Manley steel valves are compatible with
unleaded fuels and all valve seat materials.
TECH TIP #3
Maintain adequate spring pressure. Even in a stock rebuild, Manley recommends upgrading to a performance spring kit. Inadequate spring
pressure results in valve float causing abnormal stress on the valve train and limits r.p.m. potential. In a high performance, high lift application pay
particular attention to valve spring coil bind clearance. On all Manley spring kits, a minimum of .030” is recommended to achieve maximum spring
life. If your camshaft lift is near Manley’s maximum range, move up to the next Manley kit. The increased spring pressure and coil bind clearance will
allow you to realize your engine’s full potential and down the road your valve train can accept a higher lift camshaft without the need for additional
top end work. A definite money saver in the long run!
