I am guessing i need to use the Mk4 1.4 8v headgasket for the G, the question is has anyone knows if there is much difference between the ones from GSF/ECP and the VW ones apart from the price difference?
I'm using the mk4 HG on mine, just got it from G&S. I don't think you have to use that one on a 1341, as far as I'm aware you can use the normal g40 one too.
The thinner ones raise compression, not ideal on a 9:1 as it is! I've been using genuine VW for mine, Only £20 made by vitor reinz.
I'm using a metal headgasket on my 1341 engine. No problems with high compression ratio and I am pulling a bit of power however cam overlap helps keep boost down to 13PSI.
I guess it may depend on your remap.
Duck.
whats best to use with being 9:1 which is the thickest of them? ill be running alot of boost so wanna keep my comp ratio as low as poss!!!
standard G40 one
do you not need to run differnt one with being 2mm bigger bores?
nope
