Why vacuum secondaries? Are you going to be doing some towing with this engine?

I'd add ARP rod bolts to the list.

You could always adjust the secondaries with an adjustable vacuum unit. Come to think of it, why isn't there a linkage to make a VS to a DP when you floor it, like a "kickdown" function. That wouldn't bee too hard hard to make....I think. Any thought's?

The combo looks good to me, but maybe a bit high operating range on the cam perhaps? I don't know if that's considered a good performace cam or if it's a very radical one. But anyway seems a bit much, especially since you didn't mention putting in larger valves or anything..
