Gentle heating, tapping shaft endwise, oil while cooling would be a start.

I will be replacing my head soon and sounds like I should use the Rimflex gasket. Does anyone have the part number? (I apologize ahead of time if it is in the Tech Tips).

I got my last Remflex for the 235 at Summit for a good price. That gasket was the cure for an old Clifford intake I had that didn't fit for spit.

Frozen up heat riser valves are a common problem, and they're usually pretty simple to fix. Heat from a Propane or Acetyline torch ,penetrating oil, tapping the shaft side to side with a hammer, and lots of patience will usually free up the shaft. Soak, heat, tap, repeat- - - - - - -over and over. Once it breaks free be sure the flap can move through its full travel, install a new thermal spring, and press on. The thermal spring on Ebay advertised for a Jeep is less than half price of the outrageously expensive OEM style ones the resto-ripoff places sell.
