My take on the oiling system crossover tube for the small block

Any reason to not use a softer set screw? Like brass? Then stake it in, once it is set in place with Loctite.
.
All the set screws I found were stainless steel or a harden steel never found a brass one. Then I went to the drilled cam bearings. Much easier to do the bearings and no broken taps or drill bits.
