As far as cams, I was think of using comp cams xm296hr-12 (242/248 @.050, .566/.566) or lunati 299/304 ( 240/245 @ .050, .612/.612). The smalllest rect. port head I see from AFR is the 305 and I feel it is to much head for street use because I would have to turn more than 6000 rpms to take full advantage of the head. Thanks for the reply.
