I've got a couple of things for you.
I found a 10mm by 13mm shorty exhaust wrench that is really thin. It's Champion brand (the Craftsman lower end brand) that is bent in an open U shape, with the ends bent about 45 degrees. This is amazing at getting to the rear underside exhaust nuts on the exhaust manifold. No ratchet fits here, and no straight wrench will do. I'll add a pic when I get home.
BTW, be sure to use (and reuse) brass nuts on the exhaust manifold, despite their cost, and always use wavy washers as OEM, not split washers. AND DO NOT over torque! You'll deform the threads. Just enough to flatten the wavy washers. That's part of why wavy washers instead of splits.
As to valve spacers: I've had my Duetto for 52 years, so I've collected a lot of valve spacers. One cold winter I spend a nice Saturday watching Football in the garage and sorting all of them with a 50 year-old precise, calibrated micrometer. I even measured them to half step spacers. Actually the statistical breath of the manufacturing. And then came up with this (see below). There are up to three spacers in every size - Yeah, I did say 52 years). BTW, the rear side is the same, except it covers the thicker range of spacers, less commonly used except for modified valves and seats. Useful on highly modified race cars.
I ought to make a bunch of these for BB members. Any interest?
Yeah, it took a while to accumulate these. The wooden plugs are the ones currently in the car. Wrenching on Alfas is easier and more enjoyable than any car I've ever owned. My baby has aged well with me. I hope you get as much joy from yours as I have from mine.
*Micrometers get more accurate with age. The constant turning slowly smooths the very fine threads, averaging out the variations across hundreds of thread turns. Mine was passed down from Grandpa to Father to me. It's also a Starrett, ca 1920. I can measure to a 10th thou' easier than my Starrett Dial Gauge. I'm down to the oil film thickness as the only source of error.
