I bought a set,(the last time i rebuilt my engine) from honda because they were suppose to be better but guess what...my base gasket is leaking...this time i'll use cometic gaskets for the base and the head,for the rest i have a set that i bought from cyclex.I don't see why a lot of guys only use OEM gaskets.With cars we only use Fel-pro gasket and not OEM and we don't have any problem.When i can,i try to buy aftermarket parts,for exemple i've just buy my cable clutch and i bought MotionPro instead of OEM and i'm really satisfied with the quality.That's just my .02 cent
