Hey pro240c,

if you double check my previous post I said, meant that,
YOU DONT HAVE TO CHANGE RADIATORS IF CARRYING A CONVERSION TO THE STD A12 BLOCK.

And yes, the 180b radiator, I would think, is a bit to big for an a12 or a14, especially meaning that one has to drill additional holes etc to mount it in. The std a12 radiator would suffice.

Cheers
