Ok, the 1700 engine was at the end of it's lifetime for sure, eating up oil and smoking like a locomotive, because of the badly worn out cylinder set, so I have decided to change plans on the 2L project, and just build a decent new-ish reliable engine, so I could enjoy my beetle more, and with no worries. The 1.7L engine will now become the long term "all-out" project, and in the meantime, I hope the bug will be running perfectly good. I wonder why I didn't think this up earlier...
That being said, the new engine is already up and running, I did the break-in and about 400 kilometers on it already.

The engine specs are:
2.0L type4 CJ case, with the plugs drilled and tapped.
2.0L crankshaft & rods.
New Mahle main/conrods/camshaft bearing sets. New connecting rod bushings.
Webcam 86A camshaft & matching webcam lifter set.
Original oil pump.
Original 2.0L Piston&cylinder set, honed and re-ringed.
1.8L heads (41x34 valves), just a little bit ported on the exhaust side, and new exhaust valves installed.
1.7L rockers, with the 8mm adjusting screw and the hydraulic shims/spacers instead of the spring.
Scat HD dual springs with the little spring removed.
Pauter HD spring retainers and hardened locks.
Elephant swivel foot adjusters.
228mm clutch.
All the rest, like cooling system, carbs, linkage, ignition system etc, comes from the previous engine.
Right now the exhaust is a hacked up original bus one, but not for long

I'm actually pretty happy with how the engine is performing, the only problem I had was with 2 elephant foot adjusters which exploded (on the same piston), probably because of me not clearancing them well enough. I changed those with original style, and no other harm was done.
I safely took it to 170km/h and it feels like it can do more



Here's a pic that I find funny:
I can honestly say that I have a 911 connecting rod in my engine. And a 930 one also :P
