I wouldn't mind picking up another pair of 4V quench heads. I have two
or three pair of open chamber, but only one pair of closed chamber. Not
that I'm greedy or anything.
I wouldn't mind a pair of Aussie 2V heads with quench chamber, but I
don't think they'd be the best for racing, as I believe you are pointing
out and Chuck has validated since he's moved on as well.
