383 for a 67 cuda

I have been doing a lot of research on the internet and found that most people are getting about 400 - 450 out the 383. There looks like a lot of different modifications and upgrades that can be done. Different cam's, lift's, head's, compression ratio's. Is there a logical process to organizing a build? I have the block and know I want to put in the 440 crank. From here it is head's, then lifter's and cam's, then valve's and intake? Thanks guys. Sorry VAL65 for the misunderstanding that was my bad.
