I missed this thread ..Glad you posted it on another thread.
Very nice results.
Getting back on track here, Thanks Jeff. It really makes one take a step back and look at things in different ways or at another angle.
And it goes to show that port shape, proper size in critical areas and correct air speed in a well design port will make the power it should.
I have witnessed a customer spend 4k on an aluminum head upgrade, bigger/better/more everything only to trade a 15/20 point gain on one end, and loose the exact amount on the other.
In the end, it became quite obvious the "climb was not worth the view" customer tried to justify it, but failed in the end.
Pretty bad when a "top" known aluminum head can't beat an off the shelf economy 305 replacement casting.
Live an learn, it was a great lesson.
