Just out of curiosity(sic)...............

I guess it was more of an inference rather than someone actually telling me so.Like I have said before all my racing tuning experience is with bikes.I do not find pushrod engines at all baffling but my experience with things not having dual overhead cams is limited.Most of our heads flow really well stock, and usually mild porting and oversize valves are all that are needed for optimum performance.Bike cylinder head design is not nearly so restrictive or limiting as the stock heads of our poor little mustangs. I guess that the super competitive bike market forces the manufacturers to turn out good heads stock, while car manufactures stagnate and wallow in their own feces.
