The compression should be around 9.3 to 9.4 and the timing got dialed on KRE's dyno at 9 degrees. It idles smoothly once warmed up, but the EFE/heat riser is vacuum operated and just won't get happy. I'm going to replace the 190 degree thermostat in the morning and will see what difference that makes. I'm sure it didn't help that it was 98 degrees here today and high humidity. Were you running stock water pump and radiator?
