Mike @ High Flow likes to run most set ups over 200. Gotta be a reason.

Just finished running the valve lash. After two full boating seasons, we did not need to change the lash on a single valve. We could have checked the spring pressure, but we decided to wait until next year. Checking the lash on both engines took about 90 min, the KEPP valve cover system a a big time saver. If you run hydraulic lifters, how do you know if your valve train is wearing before you see broken parts?

If it's been setup on a spintron I would be equally concerned of the spring going away as the lash. How much lift is the cam in these combinations?

simple. you hear the broken parts. then you remove the valve cover. THEN you see the broken parts...

Not sure if you're being sarcastic but........

The idea is that with a solid cam, you can check lash and if something is going south, you can identify that there is a problem before it all comes unglued.

A hydraulic cam will mask small dimensional changes and the end user will not know until it's too late.

Again, maybe you were being coy?

You can do the same with a hydraulic cam. You would basically be checking the preload.

I suspect that's a case by case kind of decision where you would need to know the cam's specifics to determine for sure.
