I was using iron heads and still didn't have a problem now have aluminum heads running timing at 36 degrees no problem. My quench is .045 with flattop pistons.
Where are you located, I see bayou for your location, I assume your located in Louisiana, I'm located in Gonzales.
Across the ditch in Plaquemine. I'm pretty confident it will work. Been busy researching and developing last couple days with dyno/engine room men.
