max lift recommended ???
>When a cylinder head company (i.e. AFR ) states : 1.450" OD Hydraulic Dual Valve Spring, 120 lbs. on seat, .550" maximum lift, AFR #8020 .
Is the company (AFR) talking about cam lift without the roller rockers (i.e. 1.5 rocker ratio) or is this total lift whether using 1.5 or 1.6 roller rockers ?
