Some guy in Michigan has a pretty good-looking 1.6 core (or maybe more) hyd. head for sale. Approx. one day left on the sale....no bids yet. Opening bid about 100 clams with freight. If I was in the search for a rebuild-able hyd. head, I would sure think about this one. The cam does not appear to show any flaking. I have seen much worse.
Me no do hyd. head unless have 12-gauge at temple........
