Well, I drove the Z to work today. Vast improvement over the truck, though a radio would be nice to have.
No smoke. It's wonderful. I'll pay attention when I start it today to go home, but it looks like the new valve stem seals did the trick. Warm idle needs to be raised, but that's all that's wrong so far. I even got most of the interior panels installed last night.
For reference for anybody out there:
If you're rebuilding your Z-car head and using anything other than bone stock valvetrain parts, save yourself three head rebuilds, and throw out the standard valve stem seals. The seals you want are Fel-Pro part number SS 72686. They're for a Ford Capri V6. They fit the Z guides perfectly, and are much shorter than the stock guides, giving you lots more room for those thicker spring retainers and larger camshaft. They're also designed to be immersed in oil and still not leak, which is a big consideration if you use a high volume pump and end up with a lot of oil up in the valvetrain. Autozone usually has them in stock.
