Hi. This is my 1st post. I'm not sure if our 84 rabbit is a 1.5 or 1.6. We are changing the head gasket and want to order new 1 online. I will look for numer of holes in gasket (1 - 3), but does it matter if it is 1.5 or 1.6? Any tips on doing the heads gasket change? Seems pretty straight forward. Thanks, Ken
