QC on Performance Parts I am curious to see what type of quality control the different shops implement on their ported heads. Do the sponsors CC the chambers, intake runners, and exhaust runners of their heads and also put them on a flow bench prior to being shipped out? I know that this is tedious work...but it would take less than an hour to perform and would ensure consistent product performance. The people who are porting heads are experienced, but that does not mean that they are infallible and can not make mistakes. Even CNC heads have variations...and they are purported to be more consistent than humans. As you can see some heads make more power on some cars than others. I am just curious about how much of this is due to product deviations. Anybody willing to step up with information? I think this is valuable for those evaluating whose products to purchase. Strict QC would ensure that the product delivered is as promised.

Re: QC on Performance Parts That's a good point. It also shouldn't be considered just QC. What you mentioned as far as the measurements would provide someone with enough information that they could statistically determine (over time and quantity) what the effects of various combinations will do. I guess that's what you would equate to continuous quality/product improvement.
It would be a pretty sweet business to do this as a service, except the shipping would kill the idea. Hmmmm, still thinking about that one. I know that in performing calibrations it's best to send your tools out to a third party for nonbiased reasons. It also tends to normalize the measurements better, taking a lot of variability out of the equation in some cases.
