Oh please stop, it's blatently obvious from dozens of pictures on this site and various post on truing cranks that the answer is no, they are parallel.

Clearly the 20° offset in an RS is to stop the 70° engine shaking itself to bits

The thing that's somewhere between terrifying and funny is that a guy charging money to rebuild cranks doesn't know this, didn't check and worst of all can't work it out.
Actually as this crank rebuilder is in the midlands he's probably the one who put monkeys back togeather, that lasted all of 600 miles and took a set of cases with it, caveat emptor indeed.
