Thank you Greg! I did order the kit from AN but I was wondering whether additional items/mods were needed.

I’m also thinking of doing this. Please let us know how it goes.

If you fit a Mk3 timing cover then you can block off the oilway drilling in the case (1/4" UNC although a '71 should be 1/4"W).

What did this oil passage feed, I fitted a mk3 cover to my 73 2-3 years ago with the correct pump seal, I can't remember doing anything with that hole. My engine has been great with the new cover.

What did this oil passage feed,

The oil from the pre-Mk3 OPRV is sent back to the inlet side of the pump through that drilling in the crankcase. It's not absolutely necessary to block it off.

Does a mk3 need any system bleeding or similar compared to a pre mk3 ?

No.
