i have a white bros e-series exhuast and noticed today the bottom of the radiator is touching the header pipe, after some messing about i managed to get a gap of maybe a milimeter or so,,,,is this normal?,, i know the header gets tad warm [ ive seen it glowing red ] im surprized it hasnt melted the aluminium actually,,,, anyone else had this ,, and is there a remedy, or shud i just tap a dent in the radiator bottom to improve clearance?

I would tap a dent in the pipe before I ever would the radiator. I would be affraid of the risk of restricting flow in the radiator.

That seems a little too close. I have the WB header as well and there's plenty of space.

Double check the installation, or call WB for advice.

Are you running the WB tail section as well?
