Johnson Roller Lifters

K800 spring

I wouldn’t use them with that spring load, or with a cam that required that spring load.
I’m not a fan of the “proprietary formula cast iron body”.

I can see where they’d probably be okay for something like a Comp 20-701-9 camshaft, and the recommended spring that goes with it.

If I were building something with a solid roller cam, it’s getting lifters with steel bodies.

Those Johnson rollers might be the best thing since sliced bread....... but I’m not going to find out on one of my own builds.
