Stock port.....that's kinda funny.
It's a one off, no one has made anything like it. And I know how to make them even better, so I would change them around some, but still use the Chevy rocker system. I have tested this system to excess of 8,000 rpm.
Like I said here in post #21.............
Max horsepower with EQ heads?
..........
I wouldn't reproduce this system for less than $10,000. To
me it wouldn't be worth
my time for less.
