[Mg-t] rocker shaft?

[BOB GRUNAU]

No puzzle at all. Answer depends on the eight rockers used.
Early rockers were wide on the four intake rockers, narrower on the four
exhaust rockers, and used the 14" shaft.
Late rockers were all wide, same width as the early intakes, and therefore
needed the 14 -7/8" rocker shaft.

So I assume since the early head had the 14" shaft, it will have narrow
exhaust rockers . It will fit either banana head or round hole head.

Moss is right, late heads used 14-7/8" shafts, and wide rockers.

We have a puzzle before us:

We're in the process of a full rebuild on my TD engine (XPAG/TD2/22791,
which
had an early, banana-holes head installed by a DPO), using a (correct)
round-holes head from an even later XPAG.  The replacement head needs a new
rocker shaft.  The rocker shaft that was on the replacement head measures
14"
-- but according to the Moss catalog, the later engines take a 14-7/8"
shaft.

Did some DPO install an incorrect shaft in the replacement head, or is the
Moss catalog wrong?

Help!
