Excuse my ignorance but what are the benefits of doing this upgrade?

I'm guessing you're in Newport S.Wales and not Newport Telford... If the latter then I would be interested!

Mk2 head flows a better than Mk1 head so it will give more power & torque. It's the main difference between Mk1 (130bhp) and Mk2 (138bhp).

And the bump in compression ratio...

If you went to a mk2 head, to get the most benefit you'd want to get something to control the VICS system.
