How much worn out? My engine had 300k km on odo and still could go for 5,4l/100km on long trips within speed limits. Slightly above 6l/100 was norm, and I never went beyond 7l/100. Another felly with 250k+ was the same. Wear usually isn't issue with these engines. MPI goes quite rich during heating up. So I'd suggest to check temperature sensors, both coolant and intaike air. New lambda sensor doesn't mean it's functional, there can be faulty wiring, too. These things have to be checked with diagnostics, before you start with swapping parts. Also, haven't you changed headgasket recently?

From what I've found, late AFH has direct drive oil pump, while older type has chain driven. Crankshaft, sump and some other parts are different, I'm not sure about block.

What do you mean by "old"? Gearbox pattern? Afaik, AFH was only available in cars with 085 gearbox (Polo 6N, Ibiza 6K, Lupo) Split to two variants happened on aluminium 1.4 engines (AUA, AUB, BBY...) and 1.6 engines (AEE, AVY..) here is difference between Felicia and Octavia AEE And in this topic between AFK (Lupo aluminium 100HP) and AUB (Polo 9N 100HP) https://www.clubpolo.co.uk/topic/333514-aub-engine-code-what-gearbox-will-fit/?tab=comments#comment-2624619

I'm not sure if anyone tried it, since service manuals for alloy blocks suggests, that removing crankshaft leads to crankshaft bearing seat deformation. Also, VW didn't make alloy EA111 1.6 until introduction of FSI with modified block, so I'm not sure, if 16V block is strong enough for high power mods. Looking into manual of 6K Seat Cordoba, it seems that difference between alloy 16V 1.4 and iron 8V 1.6 is 13kg. I'm not sure how exact it is. If you wanted to try it, you need to know that there are actually two variants of EA111 blocks - one for 6k Ibiza/Cordoba, 6N/6N2 Polo and Lupo , with mounting pattern for 085 gearbox. These should fit to Felicia gearbox plate. Fabia, newer Polos, MK4 golfs (and 6 speed Lupo GTI) and other newer models have 02T gearbox with different pattern, but engine code is same.
