the usual approach would first be to drill a hole near the bottom, approx 3
mm off it.
This is to let the oil run off and thus lighten the follower. To drill
further holes in it gives a lot less effect but then you can do it if you
really really want to...
The wear results in a smaller area of contact between follower and block
which also results in wear in the block.
