318 with 360 heads and compcam build help

Establish your goal and build from there.

If I were you, I'd sell what you've got a do a junkyard 5.9 build. They are readily available at the pick n pull yards and almost always in great shape.

Alternatively, just get the 318 going as-is and have fun with it - maybe while you work on putting a junkyard 360/5.9 together.
