Re: valve to piston checking tool
Jim, Mike and whoever:
Since what you're measuring is the distance from the seated valve to the top of the piston, why does it matter what weight spring is holding the valve closed? I know we are talking several hundred pounds of pressure difference between checking and racing springs, but at 0 rpm seated is seated? Dale

Re: valve to piston checking tool
Deflection in the valve train with the high pressure springs. Try it both ways and see for yourself.

Re: valve to piston checking tool
The more rigid your valve train, the less defection, and the less difference between the two springs. I would expect a Stocker engine to see more difference.

On a Stocker, you had better check it the way you will run it. That way, you'll have the maximum lift you can use legally, and at the same time, knowing it will pass tech.
