ProComp/Speedmaster aluminum heads

I still have not fully wrapped my head around the concept of quench but from what I understand the larger flat area created by the closed chamber head will improve quench effect. I have a set of SM heads I will be using on a 360 soon so I am following the 10% of this thread that is not completely fucked up talking about rubber heads and flying valves. I'm curious what the effect will be too.

I keep trying to reel it back in and I mean just not now but a couple times through the way and I would like to get back on subject and talk about quench also and get some more understanding of with the direct change will be from an open chamber head...
On the other hand I'm not going to constantly get my Sandcastle kicked...
