318 Head Headache

I would tune what you have to the 10th degree. The next thing would be to pull the heads. Check and see what you have. Do a fresh valve job and check the springs real good. I think the 2.02 is too big for the 318 bore unless you chamfer the top of the intake side of the cylinder bore. I have run 360 heads with the 1.88 intake and a light decking with great results.
I like the cam you already have. Maybe throw some 1.6 rockers on it.
