Depends on what part of the rad your touching, try touching the tubes instead of the surround.

Not sure on that tomcat we might have to check it out it's like it is getting hot in the engine and matrix and just won't pass through the rad when the rad flushes through from top to bottom and bottom to top no problem at all and if you tighten the expansion cap the pipes go rock hard with the pressure

At least you found the problem may have started with the stat \old rad that then cooked the head gasket n head straight forward repair as long as the blocks ok
