    They have a sale and free shipping on these and im thinking of getting a set, im wondering if they're a good choice for a less than 400hp 413 bb vs the rusty swap meet fenderwells headers im running now horsepower wise.

    I have them on my 440 dart love them except getting to the spark plugs in the middle of the pass side is a PIA.

      I already have fenders cut so it might be easier to change plugs.

        I think they might work better for my small cube low hp engine than those 2" primary with 3.5" collector headers i have.

                  OH nice! I want to try a set for my 408. Might lose some power over my TTI's though. Not sure.

                    Well drivers side hits the ARP head bolts and the steering coupler, these can't be made right.

                    Figured out the steering,just going to order a u-joint and done. Heat and "massage" the headers.

                    Loosen ur motor mounts at the block and K member and move ur motor over to the passenger side. There is generally some wiggle room. Kim
