I think you will find also that standing the valve up allows for a smaller combustion chamber, therefore higher compression with less piston dome.

I have a set of Brodix -12 heads that were ported by Weldtech. I wanted to know about the heads. I got ahold of both companies and gave them the numbers stamped into the heads and they told me everything I could ever ask about and more. They were great.

If you go to Brodix website, you can enter serial number for the head and the will tell you casting date and the head type.

Since we're on "Dummies Guide to Sprint Car Engines", I have another question that I asked a few years ago & didn't really get the answers: Down nozzles: Do they carry pure fuel, or fuel air mix? If its pure fuel, doesn't that alter fuel/air mix? Do they compensate by running the injectors leaner? |

Nozzles lines up or down are just fuel, the nozzles has an air gap to prevent sfioning, that is were fuel atomization occurs.
