It’s pretty obvious by looking at the exhaust flow curve(ex numbers with 1.6 valve are higher than intake numbers with 2.02 valve thru .300 lift) there’s some sort of problem with the bench/test.

As for the ported numbers from the second bench........ I wouldn’t be happy with how poor the .200-.400 intake numbers look......... if the results were the same on my bench.
Of course....... the curve could look completely different on a different bench.
