Change anything before I start assembling?

This has been in the works for way too long but now I got back my crank from balancing and I'm read to start the assembly of my new engine. Now is the possibility to change out parts without much headaches. What do you think about the ingredients or is there anything that's a mismatch? Car is a 70 Charger and mostly street driven.
Here's what I got:

440 block (1969) - bored to 4.340", decked to 10.710"
4.25" stroke crank (Molnar)
7.100" Chevy rods (Molnar)
1.480" CH custom Autotec pistons (--> .005 below deck), 17cc dish for 10.6:1 compression ratio
Fel-Pro 8519PT head gaskets (.040" thick)
Trick Flow 240 Powerport heads (ootb)
Comp Cams XS282S cam (244/252 @.050" - lift .555"/.576" --> based on 1.6 rocker arms, 110 LSA)
1.6 PRW stainless roller rockers
B3 rocker arm geometry correction kit
Hemi oil pan (6 quart)
molded windage tray
M63 oil pump (standard volume)
Doug D452 headers - 2" primaries, 3.5" collectors
Pushrods have not been ordered yet but want to run Manton 3/8" pushrods.

Rest of the car:
3.23 rear gears (Dana 60)
4-speed with 3.09 first and 1:1 fourth (gives me a 9.98 starting line ratio)
26.6" rear tires (295/50/15)

No decision has been made on the intake manifold. I have the following at home:

Edelbrock RPM
Holley Street Dominator
Indy 440-2d

Current carb (on my 440) is a QF SS750 Annular mechanical secondaries but will change out to a Holley Sniper in the near future.

Any suggestions? Thanks!
 
I just bolted together a very similar build. Only cam break in so far but it sounds awesome!
I also went with B3 racing kit, it was spot on.
 
I used a Hughs cam. Flat tappet
