quote When your building a race engine that doesn't need to run on pump swill then you don't have to worry about quench... You want to drive with crap fuel you might want to try it... 
My discussion with the guys at Ross was a 10.5 to 1 470 that Im building. Will run on pump fuel...
I think the quench factor is WAY overrated..and the guys at Ross backed me up. Ive personally have had 2 instances with no quench and 10.5 to comp with iron heads and no detonation problems. Building another non quench motor with 10 to 1 in iron and the 470 mentioned. Also putting together a 11 to 1 512 with aluminum heads. All on pump gas. I dont expect any problems with any of them. 
IMO, the cam plays more of a role than quench...
If you look around there are plenty of guys on here "breaking the rules" so to speak.
