when u get ur new head u gonna want to adjust the vavles on it too. If i were you try to adjust the vavle first, if that doesn't work then go with a new head. Go witht eh cheaper thing first then go to the more expensive. As for the head i do belive it is a direct bolt on, but dont take my word on it. U have to find out what timing belt to use and what head bolts to use. If ur putting on the new head u might as well get some ARP head studs. HIH
