If the spring pressure is right and you keep up on the valve lash, you will have no problems. We have used the solids in quite a few street engines. If you want hydraulics, you should go with the extra travel version, not the stocker lifters.

Let me know if you need any help.

So could anyone chime in on the pros and cons of the ceramic verses the tool steel lifters. I have an R block that will have a solid in it for my next build and want to start collecting parts. This is a bracket engine (low,low 10's) and what I'm looking for is reliability.

My Schubecks worked great. I never had to adjust the lash one time
all season but, since they fell apart, it just failed one of their selling
points...........re-using them almost indefinitely.

I'd love to use another set but, can't justify the cost a
second time. It's going to be plain old EDM solid or roller.

On second thought, I might stick these back in anyway.
