Quote: Yes the Hemi is tumble ports, something a lot harder (but possible usually at the expense of flow) to achieve with a wedge.
I also seem to keep seeing guys building the new hemi are claiming no difference firing both or only one plug, what have you found?
When you think about it--How can there be the same timing lead required when you have 2 plugs on opposite sides of the chamber? J.Rob
What's a tumble port?
That's a term my Son Matt calls some of the heads I test on my flow bench. Some including some CNC'd ones sound like garbage disposals when I crank it up.
