What is a good performance enhanced stock 1600 engine

Our Beetle 1600 Twin port is getting tired. It has done 50K miles since we got it, and that was unknown second hand condition. We don't want to race, but above standard would be nice. If we can keep the 34 PICT/3 carb and the SVDA distributor, that is ideal, as they are rebuilt already. It will cost the same to have 1640 barrels and pistons. 1776 may be a bit much for the stock carby, and need a little extra machining. What about a slight cam or ratio rockers? I know it all goes together in an engine build, but I just want to see what the most an original 34 PICT/3 carbied rebuild can do, even if it is 10% above original power.

I ran a progressive for a few years

Once you get it jetted it is fine.
Bugger to get through - the jets live inside the bowl

Also one of the mixture screws lives on the wrong side of the carb

You need the "deluxe" manifold with heat for a smooth action though
