Roller Retrofit Lifter Bore Question

This is a typical “it depends” scenario.
For a mild-ish street/street strip build……. Provided the lifter bores were decent, there would no need to bush them.
And bushing them is more money than just finding another block that doesn’t have wasted lifter bores.
This is assuming you catch it at the early stages of the build/planning and don’t have a fresh build you’re considering using a roller in and discovered the bores are out of spec.
