Valve springs by Andrews
Installation is straightforward and mostly requires no cylinder head modification. They may be combined with OEM valve collars. As always, it is mandatory to check the proper height and tolerances.
Max. travel is shown without safety clearance. A minimum clearance of .050“ is recommended. Closed valve spring pressure is measured with stock upper and lower valve spring collars and stock installation height, if valve spring collars are supplied with springs it is measured with these collars. Open valve spring pressure is measured at max.possible lift. All valve spring kits are for one motor and without valve spring collars unless noted otherwise.
