Soft Break-in Valve Springs

Lunati calls for soft break-in springs to be used on their cams. I'm using a solid roller, even though I have spring pressures that exceed their rule (I have something like 260# closed 515# open I believe) for using soft springs, is it really necessary on a roller cam? If so, I'll do it but it seems the roller wouldn't matter.

Thanks, Larry

Not needed on a roller cam, for flat tappet cams with more than 125 lbs on the seat.

cam break in

Not necessary on a roller.

But when necessary. Most people just remove the center springs and start the motor with the outer springs. Once cam is broke in, replace center springs.

I agree I have never heard of using lighter springs to "break in a roller" cam. What I do with flat tappet cams is use my "break in" rocker arms they are low ratio (1.2) and that saves me the trouble of having to pull the heads apart on the car. I just swap out the rockers adjust the valves and I'm done.

You can get the roockers at www.speedwaymotors.com If you can't find them online give them a call they do have them.

Are you asking me to figure out what springs to use?
