Thread cleanup questions

Trevor B said

I want to try to clean up the head, intake, and block holes and bolts as much as possible before my re-assembly.

What do you guys use to clean up bolt threads and holes when rebuilding?
Tap and die?
"Thread cleaning tap set"

Can I wire brush my bolts with the wheel or do I need to use brass?

Thanks!

About $40 ('78 $) worth of new bolts with 4 'centerlines' cut through the threads
at the horizontal center line of the bolt(s),

Blind, Taper, Centering, Bottoming taps pitch variance is completely Mfgr
dependent & are all over the place with tolerance ...


Just My personal preference, I want to clean, not re cut.

P.s, $ spent = one time use :)
