more interested in how you ported and flowbenched the head, really...as i understand this sort of thing, it's very easy to do more harm than good. the heads are pretty well free flowing as it is, so taking too much material is a gamble sometimes.
besides, it's not like the days of yore (when ken was a wee tike) and the castings were rather poor. todays castings are pretty well clean and usually the benefit of massaging to the ports is offset by the related expense to do so.
then there's a 'race spec' port for heads, which basically relegates the motor to track use as the benefitial flow happens at higher rpm.
regrdless, looking forward to it.
