REMARKS :
#
Many different valve spring setups have been used in these engines. In most cases, the std spring can be replaced by PAC-S99008 or PAC-S90010 (check diameter). Please contact Cat Cams if a different setup must be used due to fitting, coil bind or valve float

FOR COMPETITION APPLICATIONS ONLY. Following details must be verified:

-
distance between valve seal and retainer at full lift must be 0.6mm at least
-
minimum valve spring travel of 1.0mm at full lift must be provided
-
distance between valve and piston 1.0mm (pref. 1.5mm). check 5-15┬░ before TDC on exhaust, and after TDC on intake
