If we had to try it all over again we might have used a set of 360 "J" heads with 2.02 valves

The 2.02 valves would be a waste. Even on a 340 or 360 they do not come into play until the higher RPM band is reached. In fact they can rob low end torque over the 1.88 valve head on a 340/360. On a 318 the effect would be worse yet. Some well versed machine shops told me this and I didn't believe it either till I took a set of 2.02 heads and made sure that the heads were cc'd the same and as close to equal specs as would very likely to be OEM. No other porting or machine work done. I gained absolutely nothing. Just as I was told would happen. Although they said that I could have gone the other way to but in my case I didn't. Use volocity rather than volume.
