How can I not be, the port cc on a stock head is 153 as is on the "ported"
head, chamber size is both 60cc... so according to the book, the only
difference is the valve size, so where is my orange in that? Oh, and when I
can pull $3000 outa my butt, I will test them both. So instead of a smart
remark, how about some info, not everyone on the list is an engine tech.
