The way we do it on the SBC in the dirt car is to grab a handful of different size hex nuts. Start with a 1/2" hex nut laying flat on the pickup and
place the pan and gasket on and it should fail to seat against the pan rail. It should wobble a bit because it's resting on the nut. Drop down one
size at a time on the hex nuts until the pan just starts to lay tight against the gasket and pan rail. Take that nut out and measure for thickness,
subtract a 1/16" for gasket crush and you know the final clearance from the pan. Everyone has a few spare nuts laying around and you don't
have to worry about keeping a batch of clay from drying out before the next use. KISS principal at it's best.

That's another good technique, Dale. I do have to admit though...I was sharing my simple method. I withheld the technical method that I've used every time I've designed a pickup tube to be used with a specific pan...I figured not everyone has one of these sitting around in their garage. LOL.
