At first, I couldnt see the difference between a good job, and just a decent job, or a bad job. I sent my measurements that were necessary to one of the guys on this site, and he calculated a whole bunch of numbers that really made no sense to me at first. Now that I have been on here for a while, I get more and more of what he was talking about then. He told me that the pipes werent really a good match for the porting etc...( mind you, mine had the boost port done as well), and that the port job was more suited for a set of CPI's or something. The best advice he gave me though was, as unattractive as they may look, bolt them on, and see how they feel and perform, then decide on whether to pretty them up or not.
Theyre not that bad, bad means seeing light thru the side of the cylinder, or an interior like a horse chestnut.
By the way, these ones that I have arent pretty, but they frickin haul ass!
