Point taken. Theoretical discussions often end up displays of arrogance. My bad.
Have to remind myself that it's better to be good than right!
More positive and constructive comments from me henceforth.
If it turns out that you end up with a maldistribution problem in the plenum, there are some quick/effective/adjustable mods you can make. Hopefully we won't have that conversation.
Cheers,
Mike

Mike, please don't take my late night ramblings as any form of negativity towards you. I definitely enjoy your input and bow to your tech knowledge and experience. I would prefer people did speak their mind than say nothing. We will tune with Trim and fine tune with EGTs.

it was reckoned unequal length headers spread torque over a wider rev range, varioram etc suggests the same applies to intakes.

For example, if you end up with a 1.62" ID tube which is from a 6800 RPM horsepower number (and adjusted for what kind of tube is available), then you want to hit peak torque somewhere around 5000 RPM, then you'll end up with a runner length (from bellmouth to valve) of about 13" (330mm).

I thought they would have been shorter than that Thom? Interesting. The inner diameter is more like 1.85" on ours for reference.
