360-2.02 valves Fit a 318 block with no clearance issues?

Everyone says 360 heads are too big in the chambers, but I think most of this is people reciting what they've read.

For me, a stock never shaved 318 with 1.78/1.5 valves was 66.5cc.
My 360 heads, unknown history Ferrea 5000 2.02/1.6 valves are 66.5cc

And yes the 2.02 valves fit with no necessary clearancing done to the top of the bore.
