In SS Modified most of the Auto classes get 5% or 250 .Which ever is least.
So it figures out more like 150-175 for most of everthing. I like the idea of short spots. Back when I ran my tracks in the 70's (Before the bracket race foothold) we had a "Street modified class" it was based on Lb per cu in. If I remember right we had either 5 or 6 classes and no spot was over a tenth per class. Some spotted races looked almost heads up. It was very popular. Point is some combinations can be equalized through a short spot and the spectators almost see a headsup race.
BTY: The Brodix logos for the spec heads are cast in. Bump them with a grinder or mill and it is pretty evident. I've bought several sets of their APBA and ASCS heads that were QC'ed and taken the logos out. I've flowed the heads before and after the logos and they really don't make much difference. The purpose of the logo is to stop massive porting not be a restrictor in the port.
