I used aluminum head gasket and had some leaks with it. \n\nWhat is the best gasket type, copper or maybe some Takegawa one (is it steel or??).\n\nHow much torque on head bolts, standard values or some extra maybe??\n\n\n\nIf I end up using a Takegawa gasket is there some differences between different Tagekawa head desings? I mean which one is the right one for a non Tak Honda. How thick are Tak head gaskets? \n\n\n\nDo you usually use 54mm cylinders trouble free, or is it common to have head gasket leaks?
