Resurfaced lifters

Send them to Schneider Racing Cams. The guy they use does a top notch job.

Some of us in the US have been using resurfaced lifters for decades. It’s not new.

Ive seen more done incorrectly than correctly.

If they don’t have a radius they were done incorrectly. They will look like they have a point in the center.

Most of the time that will kill a cam.
