To quench or no quench

I’m at that cross road now. I could go ether way.

My J/U head can go with a thin gasket and have clearance.
If I move to the Edelbrock head, it’ll just take a thicker gasket. If it is not available off the shelf then Cometic gaskets will be ordered.
Measure your piston to head distance and order the gasket with the amount of quench your needing. It will be a while before I can race the car. It Needs a lot of work. Changing parts or the engine is much like socks for me. When the socks are done for the day, off they go!

(Both heads need work. The Edelbrock should be cheaper.)

As it is now, the 340 is more for just moving it around. The rebuild was stupid cheap as it mostly falls under a spare parts build. It’s not exactly race suitable.
