Cam recommendation
The only tihng I'm missing here for a cam recomendation would be;
Intended purpose of the build.
Rear gear ratio
trans type (Manual or auto) and the converters stall rpm range.
While I like SG-Cudas cam, because it can cover a wide range, my recomedation may be different. His may also change with the additinal info.
Also, head flow would be great. Polishing not needed in 99% of the cases seen here.
