Turbo; JH or PL?

I fully agree with David.  Unless you have a flow bench, you stand a very good chance of doing more harm than good when you start removing metal in head ports.  Port-matching is one thing, but changing the full port cross-section is an area where few of us know what we are doing.

  Some folks love doing this sort of thing, to me I have never felt confident.  I know that it takes a lot of consistency to get each port the same pot to pot.  I know even better than porting it a certain way gives specific gains, and I know that I don't have a clue what is the best for each engine.  I sent mine off to Fumio to get the results I wanted, bankable power.  I still don't have that motor in the car yet though.

  A quick google if the internet found this.

  Not bad and it looks fairly easy. I am going to try this on the old head of the 8v first. Test the tools and how stable my hand is. Any one got a better link?
