3 more words to drive the head porters nuts.

Dad spent a very long career playing with his flowbench and heads and intake and exhaust system until he got very high numbers at low lifts. And it paid off with a highly responsive engine that flys from idle to 5800 and revs like a small Chevrolet with an aluminum flywheel. And it idles amazingly smooth and has very high vacuum numbers with a pretty good sized hydraulic flat tappet camshaft. He used to get in lots of squabbles with the big port cylinder head guys that just could never reason why low lift flow matters so much. And, he used to listen to lots of folks telling him they could not figure out why their cars were a second slower with more and bigger/badder parts that flowed much more air at .550" lift.
