to put this in simplest terms for you and im no expert but just learning while i was building my car... your heads will only flow as much as possible... so if you want to do a true cam only car... your best bet would be to pull the heads and get them flow tested to see what they are capable of... and then you can spec you cam to that... if your heads dont flow **** past 490 lift (probably what stockers are like) and your cam is pushing 550+ lift (306 cams and 847 cams) your just shooting your self in the foot and your going end up loosing power that way.... then while the heads are off you can do a valve job and springs also... but thats what i would say if your dead set on this stock heads junk... thats the only real way your going to get the best possible set up in my eyes... as said above keeps us posted...
