when replacing a 22-re head gasket do you HAVE to plane the head? my buddy's just went in his '86 4runner and people are telling him he has to plane it but he is tight on cash and would rather no if he doesn't have too.I was thinking if it looks good (flat and smooth...) it would be ok to go without it. what do you guys suggest? thanks -Corey
