thanks for the suggestions but after I've been through all these, no improvement is seen.now I think the wp is not working properly when hot

upper hose has too much pressure in it.and on stand still by 2500+rpm temp goes to +230.(my z has a goodwrench 350 with new wp and 5 raw rad and dual spal 2780 cfm fan) I have changed the head gasket with no improvment on overheating issue.any ideas will be appriciated

I almost have the same setup as u have and I also have the exact same problem as u did.how did u overcome with that mysterious overheating problem?
