Anyone got any picture of the bottom of a G40 head? I cant seem to find any in my stocks of pictures.
Reason being, have found a head here which comes with sodium filled valves and at a glance looks like it stands a chance of going...

The heads from a Gol 16v turbo in Brazil, was hoping it could be fitted to a g40, but turns out, they based the engine on the later undersquare 1.0L engine in the later Polo/Lupo/Seats.
So the valves are tiny at 22.5mm inlet and 20mm exhaust due to the bore being 67.1mm.
But for reference, the afh head does bolt onto a g40 block and doesn't need any water holes welding. Just custom pistons, and valves/cams if you want big power.
Shame though, the Gol engines come with forged pistons as standard which can be picked up for about £200, complete heads are about £500.
looking at this 3 water ways actualy need welding up along with four of the outer oilways , although the outer oilways havnt been done on this one
