I had my lifter bores bronze bushed with oiling holes as almost all of the lifter bores were worn out. The burnishing tool just fell in the bores.
Nothing is burned or scored in the valvetrain.

I would think that in over 5,000 miles and plenty of TnT runs and a season of bracket racing if there was a problem it would have shown by now. Been together since 2012.

I go through the lights with just under 70 pounds of oil pressure at 6,000-6,100 at 119 to 121 mph......no oil presssure drop
