Read here and on other boards, and even posted q uestions about 1.6 ratio not working with vortec heads b/c of the pushrods rubbing against the head. The conclusion was that the holes had to be elongated, So I went with 1.5's on mine.
It's not a myth, its a valid concern. There are alot of parts and upgrades that people do without realizing they need other supporting mods or mods to other stuff they may not even realize. They see something cool in a magazine, buy it and slap it on then later they are here asking why their junk isn't running right.
