If your engine is ticking over very quietly, beware, it might be trying to tell you something........

It tells me something is wrong, because solid lifter cams are supposed to be noisy, there's no way around it.

The clearance ramps on a C cam move at 3 degrees/.001" lifter rise. For every .001" at the lobe that you reduce the clearance (.0015" at the valve), you increase the time spent off the seat by 6 degrees, but because the difference in airflow is only 1/400th difference, you have a nett loss of overall performance & a large loss of time where valve is spent on the seat which is the time that the exhaust valve is cooling.

However, if you know you have valve recession issues, adding a couple of thou will give you a little more time before the next adjustment.

That's why I said up to .025"
