Dingle berry honing (or whatever it is called)
I sometimes will steepin the cross hatch a hair on some 4" stroke stuff along with a slightly rougher finish, for oil film to hang on, not pump, and to keep scuffing to a zilch with hyper pistons. I mentioned that a couple months back in a thread.....now it's an echo here. Shrug.
It'll run matter what 40-70 degree if ya want, but depending on which way you go about it... you may have oil diluted mixture that makes it prone to pre detonation, or blowby and oil pumping aka some oil consumption ....or it runs fine and you drive off into the sunset.
