I've found several threads on this topic, all good reading. They all address relief cuts and how they're good, but they don't answer a couple questions I have...

I have a star knockoff. It's a one piece solid CAST IRON design (no individual runners). This is the 2nd and last time i'll be surfacing and doing this. I'll be cutting reliefs, using antisieze on studs/nuts/lock washers, and copper silicone on the gasket.

1. Is there a reason why relief cuts are sometimes found along the middle of bolt holes rather than between runners?
2. Since my mani is one solid piece, does it really matter where the relief cuts actually are? (some are VERTICAL between the ports, others are DIAGONAL or some other way). In other words, does orientation matter?

most of you know what a hahn mani looks like but for reference...
