Cylinder bore cross hatch angle for Tomei pistons?

[polcastrol]

Hi all, I'm rebuilding an engine with Tomei pistons and i need to define the honing pattern of the bore of the cylinders, I cant find any specific values for Tomei pistons, only for CP pistons( see bottom of this page) . Anyone here that could recommend a good angle/Rz and Ra roughness finish? I only found this but it doesnt mention any details about this.

Any help is very much appreciated

I can't see why this would be different for Tomei pistons.
It might be different for a different material of piston rings but as we are all using the same cast iron engine blocks I really can't see why the rings material would be so different that it would require different honing pattern.
I understand the aim of blueprinting but don't stare yourself blind at all these theories.
