if it JUST the head gasket then replace it - get the head tested and skimmed if necessary.

Otherwise consider a GTI conversion, between 27-33 mpg depensing how you drive it and the simplicty and power of a 115bhp petrol engine that will happliy rev and cruise at over 4K!

yup, every bit of tech literature I've read says that...

but I've never had an issues, plus why do VW sell different thicknesses of gasket?

Because of the slight variations in piston height due to manufacturing tolerances in crankshaft, conrods, smallends, thickness of top of piston, head - they all mount up.
