This style conventional big block Chevy head is a bridge between standard conventional big block heads and spread port heads, 20* and 18* valve angle.

Yes, this is the head everyone has been talking about. RFD has taken this new casting and built several custom versions: fast bracket, truck pull, all out etc. The new SR 20 from RFD is at the cutting edge of conventional big block Chevy compatible technology. This offering raises the bar to a new level that is unreachable by the competition!
