i am going to be doing my head gaskets and i remember i had trouble with the intake manifold bathtub style gasket install. does this style of gasket have to be used? where can i get a good replacement. I have seen metal ones and ones of other material. i want it to be as easy as possible. last time i had a hard time getting the gasket on there and getting all the bolts to line up...i got it on but it took a while and should have gone a lot smoother. i dont want that problem this time. any tips are appreciated.
