EQ Iron Ram vs Edelbrock Performer

My circle track class requires iron heads. They have their place.

You have to ask yourself why a racing class would require iron heads...

Cost, correct?
A lot of spec classes try to keep it competitive rather than having the rich guys with the better equipment winning every week. Then again, the rich guys pay somebody $20k to build their motor and max out every limiting specification and end up with the best motors anyway.
