Finally the decision has been made.

At the advice of @Bodyperson I went and talked to the machinest in person about my engine build. He was very friendly and helpful he seemed impressed with my knowledge and understanding of what I'm doing. We talked for a while and discussed my build he said sounds like you got it all figured out that makes my job easy. Lol we talked a while about my cam selection and he did advise my to go one step lower on my cam. He said it will run a little better on the low end. He said the 703 will sound really good but he thinks the 220 duration cam will be better so I am gonna listen to him. So I'm going with this one
