Seeing as some parts places list all 1.3 polo mk3 headgaskets and bolts as the same (when they aren't) and G40 stuff is partly or wholely obsolete at the dealer I thought i'd offer a post to clear up a few things.
1. Stock head gasket is G40 specific, no idea why but it is. Elring do one - which appears g40 specific - ELRING 422.190. About £35
They also do a engine gasket set - ELRING 495.950 (but this only comes with 7mm stem seals - most g's will be 8mm)
2. Stock head bolts - G40 1991-94 are specific. There a M11x98mm and 10.9 grade. (many manufacturers including list normal polo head bolts to fit - these are m11x96mm and 8.8 strength and are used on mk2gtg40s and g60s amongst others). The only place i can find with the right head bolts is BGA BK4398. (not cheap - about £35 a set)
Other options is as follows
1. Metal headgasket (needs to be a smooth block surface) - vw part number equiv 030103383AH which is used on mk4 polo 8v 1.4 and 1.6 and can be had from euro car parts or gsf. This also increases compression too, so not ideal if you've got an uber skimmed head and decked block. These are about £15
2. normal headbolts - quote from a mk3 1.3cl - these are m11x96mm 8.8 tensile strength - expect to pay £1 a bolt.
(Hayesey does use the latter two in his 190bhp turbo 1272cc trackday thing - so its a usable alternative)
Max rpm/ Bartek do list g40 headbolts. But as they are for g60s too, I fully expect them to be the same as 1.3cl polo - the m11x96mm and 8.8 tensile strength.

Bartek ones are normal Polo CL type headbolts.
I'm a pikey and run a GSF metal gasket and stock Polo bolts.

Seeing as the G40 bolts are 98mm.. would there be any problems using them on a g40 head which has been skimmed (possibly a couple of times) and a metal head gasket replacement.
i intended using the Metal one ... a should note this is also for G60 charger conversion.

I doubt it. Not like they skim mms off it.

some part numbers saved from threads
Just looked up a few bits and found the current VW numbers for the following parts are
Head bolts - 030 103 384 M11x1.5 x98
Headgasket - 030 103 383 R the letter R is the important bit
Exhaust gasket - 030 253 039 A (for a pair)
Inlet manifold gasket - 030 129 717 D
Dizzy oil seal - 030 905 224 (42x4.5mm) + lil bugger 030 905 261
Camshaft oil seal - 030 103 085 A (47x10mm)
Thermostat housing seal - 030 121 119
Cambelt - 052 109 119 (special note PY 002 177)
Waterpump - theres 2 types - square tooth and round tooth cambelt
052121 005 AX (special note PY 002 177)
052121 005 LX (special note PY 002 178)
i dont know which is correct - i have a brand new in the box water pump in my garage with my 1W build but i cant get to it just yet to confirm which numbers which
the seal for the pump on its own is
030 121 043 B (4mm)
030 121 043 A (5mm) which i think its for a worn or corroded leaking block
Throttle body seal - 030 133 073 A
Exhaust manifold studs - N044 410 4 M8x28
Inlet manifold studs - N044 408 2

Hello, after 26 years and 140,000 km my PY needs a new head gasket. Which do you advise to use? my g40 have 145/150 hp
Is the head of the 3F gt engine same to the g40?
thank you,sorry for my english i use a translator

The heads are all the same I think?
A G40 has sodium coated valves and a different cam but I think every other part is the same.
Here's a link to ETKA online so you can have a look at part numbers and so on; https://volkswagen.7zap.com/en/rdw/polo+derby+vento-ind/po/1992-120/1/103-3010/
I would just go to my local parts supplier and buy a head gasket / top end kit.
