S&S T143 Specs Needed

[Ohio HD]

I have most of the motors mechanical specs, but need a few that I can't find.

(1) Cylinder height from case to the head, base gasket surface to head gasket surface.

(2) Connecting rod length C/L to C/L. I have 7.80" in my records, but would like to verify that.

(3) B3 head combustion chamber size. I seem to remember something like 106cc, but I can't find that info in my notes.

143" S&S Engine/Heads.
Rod Length = 7.660"
Combustion Chamber CC = 110 - 111. Stock.
Stock Head Gaskets Marked F and R .045" thick X 4.439" I D.
Valve Size = In. = 2.300" Ex. = 1.800"
Intake throat dia. = 2.075" Ex. = 1.605"
Valve Protrusion In. and Ex. = 2.040" - 2.050 "
I generally use S&S Valve Springs Pt.# 90-2079 on most of the 143" that come in, unless higher lift cams are being used.
Valve Spring Installed Heights In. and Ex. = 1.915" No shim. I cut the bottom spring seat .030".
Various Ex. Port Restrictors. I've had some heads come in with, and others without.

The safe way to secure them to the mill table for work.

Doesn't look like they'll go anywhere like that.
