I had a combustion chamber crack on my 235 head. I sent it to Chapin Welding in Chapin Il. last summer. They repair and rebuild heads of all sorts. At the time any automotive head repair was a flat $200. That included fluxing, flame welding the crack, pressure tesing, new hardened valve seats installed and ground, new valve stem seals. Took 6 weeks to get it back, but very happy with it. They slow heat and cool the head in an oven for welding as must be done with cast iron.
Number is 217-472-5121.
