    @andrewj1680 Yeah that head is restrictive.

    Either derestrict the head, or grab a 3MB head and you will see noticeable gains.

      @Calum thanks again, is modding it just on the squish band or is there more to it than that?

        @andrewj1680 It's a specialist job I'm afraid.

        It's more complicated than what I know.

        Mick Abbey did my head for about £35 a few years back, I'm sure someone here had their 3BN done recently. Or you can pick up a 3MB Head, but they seem to be getting harder to find these days...

              Ideal probably cheaper to get it done than get a replacement as I can't seem to source 1 and fowlers want £325+vat 😂😂 not the price I wanna pay as I plan a 200 build during the winter anyway

                I remember once upon a time, they were easy to get ahold of.

                If you give it to Mick Abbey, you'll get better than OEM as he tunes it for performance anyway.

                    @britshgigolo And this was a 3BN?

                    Wow that looks wicked now!

                    Really nice squish band. That's going to make a nice difference.
