another freaking engine build thread

allright so i recently purchased a 440 and have been looking up a lot of info on aftermarket parts and such. gonna be mainly a street only car maybe go to a drag stip occasionally not often though. i was mainly thinking the bigger sized motor i could build the least high strung it would need to be to accomplish my goals. basically just want to lay rubber everywhere. somewhere in the 550 horse 600 torque range and id be thrilled :finga:. just want some people to look over my build idea. give me tips if im a little off on things and please correct me if im wrong on anything (thats why i started the thread) budgets not a huge issue but id of course like to get the most for my money.anyways here goes.

1972 plymouth duster
727 tci super street fighter 3000 stall converter
8 3/4 rear sure grip 3.55 gearing
77 440 block .30 over
440 source 543 stroker kit ,dished pistons
Comp Cam Xtreme Energy Hi-Lift .564" hydraulic flat tappet
comp pro magnum hydralic lifters
edelbrock performer rpm heads or 440 source stealth heads (cant decide)
(not sure on rockers kind of want some tips on this)
edelbrock performer rpm intake
mighty demon 850 carb
shumacher tri y headers
some sort of external oiling system

anyways thats about all i have figured out right now but my main thing is i want it to be streetable so i know i left some power on the table with the headers and other things but im mainly just going on my theory of more cubes equals a less highly strung motor and still be able to reach my 550 horse/600 torque goal main question is which heads 440 source or edelbrock's? and what mods are needed (springs locks retainers) to run the cam ive selected? and if i can run stock rockers with any of those setups? lots of questions i know thanks for your input
