Anyone have actual experience with weber DCOEs on a slant?

I sent my SUs (plus a couple of extras just in case) to Island Automation up in Canada. We discussed the usage (225 slant) and engine specs and based on that he rebuilt and matched internally all 3 with new parts (and polished the domes for a little extra bling!). He said it should run quite well right out of the box with little or no extra tuning. I'm optimistic everything will run well.
