i had to go back and look at both cams to see why i would have recomended the crane cam over the lunati cam. I'm actually a bit suprised that i recomended a crane cam, there is nothing wrong with them they are of a very good quality i just dont look at them very often, i think i picked it solely due to it's profile.
the crane cam has a bit more duration which the 385 will like, the lunati has a tad bit more lift but that isn't enough to be felt. the reason i picked the crane cam is because it's ramp rates are a lot more friendly on a hyd flat tappet valvetrain then the lunati cam's ramp rate. your ramp rate in laymens terms is the difference in duration @ .050 and the advertised duration.
ex. crane cam: 234°-296° which is a difference of 62°, this is basically how fast the valve opens and closes.
lunati cam: 227°-268° which is a defference of 41°, this means that on the lunati cam the valve will be opening and closing (.000"-.489"-.000") in 2/3rds the time of the crane cam. 41° difference is absically what you will see on a solid flat tappet cam and is VERY aggressive. which an aggressive ramp rate means extra stress on the rest of the valvetrain.
now the crane cam acutally has more of a slow ramp rate, 62° is a good bit. if i were to build another hyd flat tappet 383 then i would look for a ramp rate in the 50° range. here are a few that i like a bit better than the crane cam, and i certainly like them better than the lunati cam.

this one would probably be my choice, i am a big fan of howards valvetrain products, i have been using them for quite a while with absolutly no problems and their customer service is second to none.

and as i mentioned before, i wouldn't go with the scoggin dicky vortec heads for 800.00 when the 180cc RHS pro action heads are the same price and are proven to flow better and flat out perform better.
the Eagle kit you chose is just fine, i've used the 4.030" kit before and it worked great for me. if you match the howards cam, a nice performer rpm intake, a simple holley 750 vac sec carb, cheap HEI distributor (60K volt), with those RHS heads, and a decent set of headers and exhaust then you will be sitting in the 410-425hp rane but the kicker will be the 440-460tq you will make, all while using pump gas.
