Wow 155... that is pretty big for stock heads.

Like I said, the bowls could use a bit more work, however I'm not looking for that kind of trouble... I would like to maximize the potential of these heads... but I also want to keep this thing problem free. I'm guessing here, but I think I'll reach a max of 145cc on the intakes when I'm done. I'll check out an exhaust port tonight after a little more grinding in there.
