Again, just to help another club member in the future, and avoid a similar headache:

Things we can learn about porting:

1. Research the topic, confirm what you're looking to accomplish, and that the shop doing the porting, understands this.
2. Ask to inspect the head upon return from porting.
3. Confirm that the head has been properly flushed, or that it's part of the re&re. (another member lost a turbo, likely due to extrude hone abrasive left in oil passages)
4. Provide parts and/or gaskets that will mate up to head ports.
5. Always use new gaskets, and new bolts (where stretch fit is required, ie: torque spec is XX ft-lbs, plus YY degrees aditional)
6. Inquire as to warranty, what it covers, and what it does not.
