First of all, you'd have to find a source for them. They are not available to the public at any cost, and six years ago they were $47 each to F1 teams.
Next problem: there's no way to make the F1 plugs fit unless you make an adapter and are able to find a tap to make the proprietary threads for them, which appears to be M9 x.75 at a glance. The adapter would need to be a countersunk affair, since the entire spark plug is approximately the length of the threads on a SBM spark plug. You'd also have to match the angle of the F1-only tapered seat.
Then, you'd have to find someone on an F1 team to give or sell you a spark plug socket, which is a special tool solely for this plug. No, the Snap-On guy doesn't have it, nor will anyone ever outside of F1. It would not be an easy tool to make, either.
Assuming you overcome all that, now you have the problem of plug wires. There is no tip on this plug on which to put a plug wire, nor is there enough ceramic for a boot you could possibly acquire. The end of the wire pushes inside the plug, not over it--spark-leak city without the correct wire ends.
After you overcome all that, you're ultimately left using a plug for which I'm aware there are no published specifications as to heat range, plugged into an engine that can't possibly make use of them since A) though the plug is centered, the Alfa head is nowhere near a hemispherical chamber shape--it's a pent-roof design*, and B) the pistons are not designed for a surface-gap plug of that size.
* Yes, I've seen Alfa heads, and they don't even approximate a Hemi. They're far closer to the polyspheric 318, actually, and the poly is much closer to a hemispherical chamber than the Alfa engine, as is the infamous 1.6L used in Ford Escorts in the '80s.
