Same valve train too? A local guy, has a 190 AC SS Kept blowing the head almost clean off, almost 200 psi of boost, when it was rebuilt, found 3 rods were bent, replaced, cyl head was salvageable, or so he thought, well it blew again, found 2 bent valves, from the old head, bent valve guide. Said it was warped from the excessive heat. Since then, it has a new design in the short block, and actually was able to lose a turbo, and still make the same amount of power, back to 2 now, now it breaks input shaft clean in two, took 3 of them, bigger as they went till it held,, won down in Farm machenery show last year or the year before in the lite super class. Have not heard much from him on that tractor,, might see him later this month at a pull. But it is still running. Just thought the valve story might interest you. He says it back fed into the turbo, pressurized the cyl at the wrong time when the valve stuck for a split second. Chad
