Is Quench Required?

I had and still have the closed chamber Edelbrock heads. The gas we have here isn’t much different than what is sold in many other states.
A 5 gallon pail of 110 octane was $55 in 2013. I can’t imagine what that would be today.
I've seen lots of guys here complain about it. I don't know either way since I don't live out there.
