I have always used comp cams

I've been using comp cams lifters for almost 10 years. These specific lifters are very well suited for fast revving high rpm valvetrains. Or applications that will be at higher rpms for long periods of time. These will allow you to spin your engine as fast as you could imagine spinning a flat tappet cam shaft without bottoming out or causing coil bind issues. They are a little soft during initial valve lash adjustment before they have been ran, so I recommend re-adjusting valve lash after break in to ensure you didn't adjust too tight on the first run. I had one lifter years ago come apart due to a loss in oil prime, comp cams was more than happy to compensate me for the replacement set. Overall 10/10 recommended for any sb/bb chevy build.
