Which head gasket is suitable?

[GTI-R Kid]

Hi guys

Just got a quote for some Cometic headgaskets, but I don't know which is suitable for my preferred application. Engine will be running 87mm forged pistons with a target of about 330bhp, but I don't know which of the list below is the same as a 1.2mm headgasket. Are the extra oil holes mentioned a good or bad idea? Any suggestions as to which one would suit my needs? Thanks

You need be looking at a GTiR specific one... Not just an SR20DE one... Water and Oil ways are different i'm sure of it...
