commando's vs. eddie rpm's

Just a differnece of opinion BJR, nothing more. I dont think they are too big. Apparently there one or two who also dont think they are a problem. I know there are guys that can't ge the numbers you do with that setup. I tend to think more in a "not everyone can do that" mind set. The heat thing isnt BS. But, I think in a lot of cases, there's so much concentration on it that it becomes larger in the scope of things than really it needs to. For instance...I like to build tight quench engines. It makes no difference to me if it's iron of aluminun. So long as the distances are right. I'll run a dish if I have to witha quench pad to get it. If you reduce the area the heat is focussed on (small, tight chamber) you will inevitable keep more heat in the chamber, making more power. Also, the outer reaches of the chamber will not get as hot, or transmit as much heat away because of this. A good quench engine has little soot or markings on the quench pad or matching chamber quench area. That's because when the biggest heat is produced, there isnt much there to burn, thus it stays cooler. Now, if you build a large bore low compression enigne with no thought to quench, then the whole chamber (or much more as a percentage anyway) will be exposed to, and transmit heat away from, the chamber. That's when you want the extra point or whatever. I love the Magnum small chambers, and I have milled big block RPM heads to get them smaller and keep the distances right.
