Dual Valve springs?
Thanx Steve
against the piston? a dual spring setup has two spring so that if the outter spring breaks the smaller inner spring will still hold the vavle up and will allow you to limp home until you can change the spring out.i ran the Rev dual kit with my tr230 for my first set of springs and the 2nd set i went with the manly kit. the 230 isnt an overly aggressive cam with hard lobes so a single spring will work just fine
