That casting number identifies a standard 202 head from an HQ, HJ, LJ, LH or very early LX (pre-ADR27A).
The L is cast into the regular, large chamber head fitted to 179/186/202 engines.

If at first you don't succeed, just call it Version 1.0 |

Could it not also, with small spark plugs and adjustable rockers, be a late HG 186 head, or an LC low compression 2250 or 2850 head?
I thought XU1 was normally, with some variations, 2817134.

YT head is just any head that has been modified by them.
Most valves have YT on them and are flat on the base of the head.
You look at the intake port and you will see the whole casting has been cut out and replaced with a tube on red 6 cyl.
