How do you tell what sort of rockers you have....
And does having swivel feet do anything?

no swivel feet does not mean a thing.

You can measure them by useing a dial indicator on the rocker. Push it up 0.100 " on the push rod side, then measure the downwards movement on the valve side if it goes down 0.110 " then you have stock rockers ie 1.1 to1

Like wise for other ratio rockers etc etc.

if they were 1.25 to 1 then the valve side would go down 0.125"

I read it on FACEBOOK so it must be true

Tassie do you know how to set up the rocker geometry " its a Black art ".
not really just need to get maximum lift by adjusting push rod length or rocker height so that at half lift of cam the rocker is at right angles to the push rod........ " clear as mud ???? ":thumb
