Factory hydraulic roller LA cam advice

Jaken,
Keep in mind that many 'power adders' are what I call 'torque shifters'.
Your original parts list is well thought out & on the money for your needs. Any dope can fit the largest carb, the largest intake, the biggest cam, the biggest XYZ...& end up with a dog. It takes smarts to select parts that will work in harmony to produce the desired result.
Two 'torque shifters': big duration cam & open carb spacers on dual plane intakes. Big cams shift the low end tq to the upper end; same with carb spacers but probably by a smaller amount.
The parts you nominated should work well with your 3.23 & c'ter to provide a nice balanced combo.
