I'm sure that this is a thread that T. Cotten will respond to - he is the expert, but ALL responses are appreciated.
I have replaced the manifold inserts in my '47 FL, but am having trouble installing the rivets. After peaning the ends, they flatten out and I can't get the rounded look on the peaned head that is proper for a tight fit.
I bought a bucking bar, but can't find the tool with the proper concave rounded tip for forming the head.
Also, should the rivet be heated cherry-red before peaning so when it cools it shrinks and tightens - or will this crack the cast Iron head casting?
Does anyone know where to acquire the correct rivets and tooling?
