I lost a head gasket going ported heads,ported inatke,1.6 rr,new cam. I going with all new head hardware after I port heads. Any parts besides timing chain head set.o2 sensoe and spark plugs I should be thinking of. I am thinking of going new water pump and dynatech.

 

OEM replacement opti. I don't see a point in getting the Dynatech....it's still an optispark and it's overpriced.
