Without detracting from this excellent topic....
I would be surprised if there are really any measurable negatives from Mexx's polished ports,
other than the time it takes.
I too read somewhere about all the percieved problems with polished ports,
but I know that I can measure, and feel, the difference
between a rotary-burr-finish and that of a sanding roll.
You have to be careful/sceptical of any data that is sourced from companies that sell products and services.
I think there is a lot of old wives tails and theorys that are out there,
and in the old days it was false representation in the magazine and text book media,
but these days it is the internet as well.
More often than not, the beneficiary is a company/individual because
it may be worth a sale,
mean less work for them,
or simply to give their opposition some misdirection.
I'll bet not many people have done a real VALID comparison with the "polished port".
My guess is that it MAY BE? worth something in the power stakes,
but not a good return on the investment of both time and dollars
for both the porter, nor the customer.
...and besides any valid comparison must have a unit of measure,
so is worthless without some measure of the surface finish
at which the benefits can be measured and compared.
Among other areas of interest regarding beneficial pipe dreams are :
bore hone patterns can only be done on one brand of machine
valve jobs ditto
cast iron barrels are no good
long rods are better
short rods are better
porsche shrouds are no good
all oils/additives except mine will cause engine/trans failure.
cryogenics produces measurable benefits.
line boring will make your engine blow up
coatings are worth the money
and I could go on.
Yes, some of these things CAN be beneficial and some not.
With some logic and common sense, you would have to agree that
accurate and precise machine work,
and meticulous preparation,
and good tuning
are always more of a winner than
some perceived magic pill delivered by a witch doctor.
Most will probably totally miss the point i am trying to make,
I I guess that is my own fault for breaking another golden rule:
I can "complicate simple things."
