Does anyone have a picture of basically the porting limits on a 6 port engine? I want to get creative, but I need to know how far I can go. If not, where can I buy a crappy housing to practice/explore on?

One other question: when porting, is duration or pure size more important?

 

You've seen that pic of the Ito part in the above thread? That looks pretty good size to me.

 

You could only go slightly bigger than I did or your through the jacket.

 

he said 6port!!! but that looks good
