We use the S&S cylinders and various cams to establish a 124".
Last set of S&S M8 piston/cyls were -.026" below deck.
A lot of "shops" do NOT have in-house capabilities to correctly address that.
We do.

How do you address it? You take material off the bottom or top of cylinder?

Generally, material is taken off the bottom.

What's recommended to be changed to feed this beast?

Tuner, clutch upgrade, new head bolts, SE manifold, pipes. If you want a little more, port heads, add TB & injectors.

Any recommendation on a specific throttle body and capacity injectors?

If you get the SE64 TB, it comes with the aluminum manifold. That manifold can be cleaned up a little.  The SE 5.5s are reasonable priced, and will feed it.

My cylinder guy always uses the bottom to insure the base is 90° to the bore. If the top needs cleaned, he dusts it first, then takes the required amount from the base.

Brian, I'm assuming he would true the bottom (or at least check it) first so it is jigged square and then go back after resurfacing to trim to length?

Bill trues any cylinder base before boring, even if the application doesn't need checked for deck. He also checks bore alignment to the base before doing any work. When a guy has bored no telling how many thousand cylinders over 40 years, he's run into everything that can go wrong or arrive to him wrong.

This spigot is .027 thick. Not getting anywhere near it. The top was true to the base before cutting within <.001

We have recently had a broken spigot on a 107 bored to 117 cylinder. I am curious to hear of anyone else with a similar experience.
Is it possible that over tensioning the the cylinders could render them out of round and risk this malfunction of the spigot?

Mounted in an expanding mandrel, both cylinder head gasket surface, and cylinder base can be true in the same "chucking".
100% dead balls true to bore C/L.
