    Default MSA Header problem

    Anybody have problems with carb clearance on a MSA header ?
    I bought a MSA 3-2 coated header for my 260 and have since sent it back to them. I believe it's badly manufactured since on bolting it up the carbs(early SU's) are essentially touching the second pipe. There's plenty of room for routing it so there'd be much more clearance, like the other five pipes. MSA says it's bolted up on their showroom floor and has an 1/8" clearance with same early carbs and E88 head. I've never dealt with a header before, but considering the heat issues with the car I think I'd be insane to have so little space there. Has anybody run into this issue before with this header ? Has anybody seen that little clearance before and not had problems ? Any suggestions for alternatives ?


    Thanks,

    Default I had them once

    Didnt have a problem with fitment though, and still had enough room for the heat shield.

    Personally I like the 6 into 1 myself.

    Default Thanks

    Thanks for the replys gema & ZmeFly.

    I did search for like problems and found
    bottom end interference problems but no top end. But, most of the headers seem to be 6 to 1 and not the 3 to 2.

    So my choices are 1) Get money back & buy a different header; 2) Get that header back from MS and see if it makes the heat problem worse; 3) Replace my stock manifold(cracked) & downpipe (warped flange).

    hmmmmmmmmmm

    Just out of curiosity, do you have the phenolic insulator spacers on the intake manifold?
