Adding the ECU chip upgrade (It is not too late...) and looking for ratio
rockers?
Check out the roller tip rockers from Pauter Machine shop.

They cost only $330 from a vender in the current Hot VWs magazine.

Maybe another list purchase to cut cost...?

The roller tips help to reduce side load on the valve stem.  With the
increased valve lift from the rockers, the side load can increase and might
cause early valve guide wear.  I added the swivel tip, 911 style, I just saw
these rockers and they look cool.
