60's- ported vs stock heasds id like to see some comparisons between 60's before and after head swaps. im thinking larger ports will lessen the low-end power? resulting in worse 60's than a stock head may. obviously the ported head will pick up farter down the track over the stock head though. anyone have some before and afters?
