tech questions for my 360

2.02 Intake valves are of little use on an engine that is not regularly turning in excess of 6000 rpm. For a street motor the 1.88's are more than adequate and arguably will make more power in the low mid range than a head with 2.02 valves.

FWIW, all 340/360 heads up to the magnum head have the same port size/shape and all have the same potential for making power. Magnums have a much better exhaust port shape to go with the modern high swirl closed chamber.
