Hi old 28,

Imagine you are expecting more HP with larger intakes, and ...........

If you would like, you could call Mr. Ron Kelly, (advertised in The Restorer), where you can learn from his dynamometer Model A engine testing experiences where he found the most effortless and most inexpensive method for increasing Model A engine horsepower by his directions on performing mild engine "porting".

For example, using a Dremmel tool grinder to smooth out sharp corners in the intake & exhaust ports; rounding and removing the sharp metal lip on bottoms of valves & slightly rounding 90 degree tops of valves; smoothing sharp corners on bottoms of valve seats; smoothing sharp corners in intake manifold; etc., etc.
