the profiler or brodix aluminum heads would be far superior to the ported stock iron heads.
the 10:1 compression , scat rotating assembly is a good idea as is the edelbrock air gap intake , If personally suggest finding a 7-8 quart baffled oil pan that fits the cars chassis, a 650cfm- 750 cfm vacuum secondary carb
due to the cars weight and gearing ID suggest a cam more like this, as a good performance choice and about 9.7:1 compression

with a 3.73:1 rear gear and a 700r4 over drive transmission with a 3000 rpm stall converter
or you could maximize the peak power if you boost the compression a bit to about 10.3:1 and use a cam like this with the same stall speed and rear gearing.
but at the cost of a slightly lower off idle torque and a rougher idle.
keep in mind that youll be using that off idle to about 4500rpm power band about 90% of the time while driving on the street and rarely use that 4500rpm-6300 power band so yes it might not seem important but in real use it will be!
