Engine Overheating 95 gt HELP

So first off i have a 95 mustang gt has I've been fighting an over heating issue for a while now. I'm lost now things I have replace

Waterpump
Tstat
Hoses
Coolant temp sensor
New dual core aluminum radiator
New electric fans
I've flushed the coolant out number of times just got done doing headgaskets on it and yet it still wants to run hot car does have manual temp gauge. As of today I straight wired the fan and seemed to help some I'm lost at the point and just wanna enjoy my gt again been fighting this issue for months any ideas or help would be greatly appreciated

Also little more about the car it does have mildly ported and polished gt40p heads with trickflow valve springs mac heads. Also doesn't have egr or smog anymore (don't know if that has anything to do with it )

What temp does it run?

It's got to 230ish then I cut it off because I don't want it getting to extreme temp I know 230ish isn't good either though.

Overheats sitting still or driving. Tstat isn't in backwards. The problem was there before doing the head gaskets and the old ones were not cracked anywhere, also didn't use my stock heads as I didn't know if they had cracks in them and I had a set of gt40p's that had already been to the machin shop so i knew they were good to go. The temp gauge I'm using is equus manual 6000 series not even 3months old so don't think it's off I guess it could be. The rad I got from pro tuning. I'm just lost and ready to crush the car but I've got to much invested to give up now
