    Question for anyone about to install (or have installed) the headers. (I just received the short tubes, still waiting on long tubes, so not sure if they're all like this or just every few or whatever). Anyway, There seems to be a bunch of extra weld on the inside of the flange, where it sits against the motor. I suppose my question is; Does anyone know the diameter of the ports on the block? If anyone is about to install a set of headers, can you measure them? I'm trying to see if I need to grind down the welds a little or if the exhaust ports are small enough that I wont have to. I can always measure when I install, but like I said, I'm still waiting on the long tubes to arrive, so my install day(s) wont be for a while and if I can get ahead of the game here, it'd help on install day.
    Heres a pic for reference.

    Just realized its not real easy to see what I'm referring to in that pic. I'll edit it w/ arrows to point to the areas I'm talking about.

    I'm really hoping the ports on the motor are small enough where I dont have to grind the welds down. It'll be especially worrisome if there is a significant amount to remove, b/c building the weld upon the other side would require the removal of the coating, making a real project out of it. A small amount wouldnt be as big of a deal b/c there seems to be a good amount of material there.

    i got the shortys but mine dont look quite that bad, a couple of ports look kinda bad but not as bad as those. if you want i could post a pic of mine tomorrow. I have to ask why you got both short and long tubes? Gonna dyno them?

    Sure, if you want to post up a pic, that'd be cool, just to have for reference.

    And yes, I plan to dyno stock, LT and ST. Whichever graph suites my needs best I'll keep and sell the second set. There just isn't any real info about what either of these headers actually produce. However, if I have to do just as much cleanup work on the Long Tubes as these, I'm going to start to get annoyed at my decision to get both. (bonus for whoever purchases the set I dont use though) There is also a little welding splatter on the inside that I need to smooth out...nothing as serious as the careless, fat welds, but still something I need to address.
    I guess I can't expect too much for 360.00 headers, but the way everyone talked up the quality of DT, i'm a little dissapointed.

    Take a dremel to those welds. Make it as smooth as possible. I have minor knowledge in porting cylinder heads. $0.02

    Yep, thats the plan. Just want to see how much I need to take off, which is why I was curious about the ports off the motor.

    Ports on the motor aren't ganna matter much. I would just grind the weld down to even of inside tube on the headers.

    It would really only prevent me from having to remove more than whats necessary.
    (exagerating, but.....)If the motor ports are 1", the header tubes are 2", but the welds reduce the intake to 1.5"s, I technically shouldn't have to remove any because motor isnt trying to push air through more than that 1" opening, which the flange ports accept, even w/ fat welds.
