Here is a picture of the new RDP-SBX Australian Small Block Chevy Pro Stock head. I found this picture on the Speedtalk forum in the advanced tech forum. The first thing I thought of was how much it looks like a Cleveland head. Did you guys get the same first impression? This head made 1140 hp on a 399.8 cid engine (I beleive N/A). If Ford had made a Cleveland head with the intake and exhaust ports raised up about one inch there still would not be a better head on the market even today. The 351c was way ahead of its time, even though it was a compromise to install in a Mustang engine compartment.
