That is a REALLY good article - and pretty much bang on with "standard practice" for many years since on pre-TDI 8 valve engines.  BTW: if you haven't ported an IDI - you haven't lived!  Freeing up the airflow (including exhaust) makes some fantastic power AND economy.

I'd love to spend more time on something like this.

I've learned for years and years how to blueprint and port 2 stroke engines [motorcycles/jetskis/even garden trimmers :P ]to increase efficiency and double the power output, but when it comes to 4 stroke engines, I'm clueless.

I'd love to have a benchmark freshly rebuilt properly broken in engine to compare towards a ported diesel engine.

Thanks for posting this article.  I was looking for it to reference for our LeMons rebuild, but couldn't remember where I'd seen it.  Googling for "Vizard article VW engine" brought it right up.  8)

I got a quote of 300 to refresh the head and 400 for a port and polish.  A shop near me has the flow bench and setup to do 8Valve VW engines.   I can't wait, I've heard good things about doing this!

It appears that the link to the article no longer works?
Shame as it was a good read! Did a bit of googling, but can't find it anywhere on the net.
