What are some advantages to Porting and Polishing the inside of the Manifold?
I was looking at Marcus' Fotki site and saw these. I was always curious of what this does to performance.

A few of us just had this done...>>
Manifolds are just going on as we speak. It's the extrude hone process...Flow bench readings indicate about a 15% better flow. While I haven't driven mine yet it should result in some incremental gains. Greater efficiency, faster spool, better responsiveness...<ul><li><a href="http://www.extrudehone.com">http://www.extrudehone.com</a</li></ul>

You could have saved a bunch on the group buy!
A polished/ported Wilson manifold which looks the same and returned the same results retails for about $1,000. Several here (GesTTalt and ZGTT) have one...
