i have a gsr block and a b16 head what head gasket should i use and what timing belt

 

dohc vtec head gasket have used both gsr and b16 head gasket had no problems with either , as far as the timing belt it depends on what water pump your using if 22t water pump gsr/type r timing belt , if you using the ls water pump ls timing belt but more then likely your gsr bottom has a 22t water pump
