Hi, my name is Massimo

Please click below for the valve clearance page from Giulia SS user manual supplement #884 R1 dated 03/65.
Jim, may I butt in? Isn't the valve clearance predicated on the cam rather than the engine type..? I think a cautionary note to the poster would include a question of what the cams are on a 50 year old car. Also some heads get swapped around over the years and cam timing marks are a bit variable based on where the head came from but won't effect valve lash.

In some cases, yes (the 00548 engine comes to mind). The 00121 engine was fitted to two models; the 10118 Spider Veloce and the 10121 Sprint Special. Both were fitted with the same 101.21.03.200.00 cams with identical clearance and timing specs. Of course, components could have been changed in the 50 years since the cars manufacture and use of a non-original cam/head may dictate different settings.

Cams & Specs for timing

Isn't the valve clearance predicated on the cam rather than the engine type..?
Commonly that is correct because of cam design (a slower opening and closing ramp)
However with the 1300 Veloce and 1300 S.S. the same cams were used with significantly different lash settings and Lobe centers.
Both used the 10106 03200 00 cam #s, but the lobe shapes were different int and exh. They were only fitable on the correct side where the timing mark (only 1 per cam) would show at the top..

Veloce:
.015 int. / .021 exh, and LCs of 104.5 int and 106.5 exh (to improve low end street drivability (LSA of 105.5)
Sprint Speciale:
.011 int./.019 exh., and LCs of 99.5 int and 105.5 exh. ( this expanded overlap and tight LSA 0f 102.5 would result in the well known poor idle and no low end torque/power.)
