Hello All,
just thought about putting this thread up,
on how a cylinder head inlet/exhaust port polishing makes a difference or not?
Did read here how polishing makes fuel droplets on the port walls,
and how Oldjohnno has mentioned in the past about fuel droplets are good in the red head.
On the polished red head of mine, I had noticed black carbon build up on all the inlet port walls,
when I had to change the extractor gasket from the often occurring exhaust port blow out's,
and I say that port polishing does not help when the carbon build up happens.
What are all your experiences with port polishing, as some say to do inlet's, and not exhausts,
and how often or how many times do you keep polishing your ports?
