Don't know too much about the Pro Action heads forst I heard of them was 2 years agp probably not too bad.

I do know the Sportsman II heads are one good head for the money, will support 500+ HP :D

The Money Pit

I was very interested in the Pro 220's for my 406,and actually ordered a set. After 2-3 months,still no heads,I decided to get the AFR heads instead.The AFR's were bolted on the engine,and the guy I ordered the Pro's from called and said my heads were ready.He completely understood why he lost the sale.
Bottom line is they're made in New Zealand,and from what I hear they flow like a wind tunnel.I did read somewhere they tend to twist the facts in the flow tests by running larger ports than advertised.The 220's actually measure 225,and when compared to the AFR 195's flow fairly well,but then again they're 30 cc's bigger.

I am sure that MountainMotor will chime in here as he likes these heads, thinks that they are a great deal for the $.
