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. https://www.nopistons.com/forums/pub...IR#>/smile.png

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

he said 6port!!! but that looks good
