I'm in the middle of a 406 build and I've come to a crossroad.4bolt ,gm crank, flat tops 10.5 1, mild flat tappet, roller everything, Vic Jr coming out for air gap, ported camel humps. I have a choice to install AFR227 with a matching cam. Kinda new at this and looking for around 500hp for the street mostly. Don't have the specs on the cam yet but I got 3.73 gears posi. Any input would be great and I apologize ahead of time for any dumb questions.

BTW going in a 68 C10 SWB
Flat tappet is going to be replaced with the new hydraulic roller.
