i am very late to this party but if it is cam OR heads get the cam and do the springs.
The 317 heads work pretty good with FI.
google/youtube stock48 nova. A stock lq9 with a cam and a newer s476 turbo went 8.39@160+ in a Nova on pump e85 and a truck intake manifold.
He is pushing that motor hard but those numbers suggest he is pushing the 1000hp threshold.
So how much power did you want to make?
