JSUP, I'm not a Dart hater. Given the 11 CC variance from spec, I would have to think that is a tooling issue. I suspect the heads are larger than 180 CC by design. Since the heads are CNC machined, the heads would not have that kind of variance as a result of machining.
I didn't throw Dart down the stairs. I reported my situation with them. Simply put, the "part didn't match the print". It's not my job to do Dart's QC, and I have no interest in sending the heads back. They're finally going on my engine. As an aside, I'm friggin sick and tired of those making money off the automotive hobby not delivering what they claimed, thus my "you get what you pay for rant." Quite frankly, I do not believe that to be the case the majority of the time. It only applies when dealing with an honest person or entity.
I'm a big fan of small, efficient, ports. The quality and volume of flow matter. This engine won't be dyno'd, but it will be taken to the track. My car is fairly well sorted, and the proof will be in the MPH on my slip. The heads/cam will deliver or they won't. It's not a direct A-B test, but I know exactly how the low-rent parts performed, and that will serve as a comparative basis.
WRT, the ring issue, if the rings do not seal that would cause issues regardless of the head on top, be they new rings mis-matched to a cylinder's finish, or worn rings.
Look, having an issue with a product or it's marketing does not make anyone a hater. Cite me.. and I didn't say YOU threw them down the stairs I was waiting for the onslaught from others...anticipatory strike.
I don't dis agree with any of that, other than what I suspect is the definition of "small efficient ports" sounds a bit like marketing to me. But that's neither here nor there. (so where is it?)
I think Dart should address the issue and I posted on their site to see their response.
I am in COMPLETE agreement with you in terms of "get what you pay for", and "advertising matching delivery".. Perhaps, and I don't know if there is, there is a good reason. Let's see what they say to the link and we can decide to accept it or not.
To my point on the ring issue I was simply pointing out this overwhelming compulsion people have with flow numbers, at the expense of understanding what is really important, more so than flow numbers, in their motor. It simply strikes me as, well, stupid to know all about flow numbers and nothing else about the important parts of your motor. I find it an interesting study in human nature to place such importance on one particular item neglecting everything else.
