Does the duplex set up require any modification to the timing cover? Specifically on a later A+ 1275New Chain = New Gears. I never even bother looking at the condition of what comes off.
As Unburnt suggested, a Duplex set up for a Road Car.

I'm doing a 1310 rebuild on my A plus too and went for Swiftune's super lightweight simplex set. It has mutiple woodruff keyways which allows a lot of adjustment without the need for multiple keys. Comes with IWIS chain. I believe the 1275 A plus timing covers need a bit of hammering to fit a duplex. Fits in with my reduction of rotating/ reciprocating mass philosophy.

Most A+ covers have a dimple in them, looking from the front of the cover as it would be fitted on the engine, it's at about 4 O'Clock. These need leveling out with the rest of the cover. Some have said the reinforcing ring (or part of a ring) on the covers that have the Oil Separator also need to be removed, however, I haven't found I've needed to do that.
Apart from the mods to the cover, there's also 2 countersunk screws that need to be fitted in place of the 2 hex head bolts at the bottom side of the engine plate.

Just to follow up on what I decided.
I was going to go with a Simplex ISWS Chain but needed new gears as well so I ended up getting a MiniSpares EVO non-adjustable Duplex Setup.
Still need to modify my Timing Case - and flatten the breather.

Is this the dimple you’re talking about?
That's the one

How much do you shave off? Looks like if you were to take too much off you’d make a hole exposing the inside.
No Shaving !
Put a steel block under it and use a Dolly on the Inside, then belt it with a hammer
