4k gov springs
 

would it be ok to put 4k gov springs in my 94 12v cummins with a 0 fuel plate,4'' exhaust,bhaf and star wheel turned thanks

I would add at least 60# valve springs.

I getting ready to install mine tonight. 100 plate, 3" exhaust

just 60# valve springs? and how much of a difference will i tell?

night and day. best mod you can do but install 60lbs springs if you use 4ks

how reliable will it be for every day driver as far as bottom end and cam and all of that wil it hurt anything?

4Ks are fine for a DD. The biggest risk is floating an exhaust valve if you stick with stock valve springs.

anyone had any problems with valve beat in? and how long does it take install these?

whats valve beat in?? 30 min for the 4ks and a hour or so with the valve springs, the back 4 are a bear.

Do I need the titanium keepers and retainers? If so does anyone know where to get them cheap?
