The DWUR has another issue. I don't know if my fuel head is modded - but the car came (ex Japan) with a bit of a strange fuel system and a host of fuel issues. Took a lot of time on the Pelican forum for a 930 newbie to sort them out. As far as I can see, the head is stock, but I have long been puzzled why it runs on boost best when I cut the fuel dump off completely. If the Imagine Y slit mod is visibly different, then I am sure mine is stock. I have inspected it closely. I have considered buying another head for it to settle the matter. But I also invested a heap of hours making a new fuel piston for it too - which cured most of the issues.
I think I made the right choice switching to your headers by the sounds of yours and Jims comments. I wouldn't know a good collector from a crappy one. I am presuming you are referring to the 3:1 junction. I dumped the heat boxes because any weight that is not contributing to speed is excess baggage. Chopped them off when I had the engine out last.
