Here's a couple of things to think about when running slicks on low air pressure.

If you run the tires "tubeless" you will will not have the issue of pulling the valve stem out of the tube if the tire slips a little. NHRA rules require metal valve stems, not rubber. Make sure you can see the studs coming through the lug nuts, do not use solid end lug nuts. You should always put a paint mark on the tire "in line" with the valve stem so you can monitor if the tire is slipping on the rim. If you do choose to run tubes, they add alot of weight to the wheel/tire package, and will pinch the tubes on the side wall if you drive them very far at low race air pressure. M&H slicks work fine mounted tubless in my experience. Make sure you run a wide enough rim to allow the tire to lay flat on the ground at low pressure. I would not worry about adding screws until you determine that you really need them to fix a problem.
