just looking at the specs for both the W124-500E and W126- 500SE.. the w126 model v8 is a bit underpowered.. just wondering if its woth putting the cylinder heads from a w124 model onto it.. there is a 80 hp diff .. and i see the bore and stroke are both same seizes except that one is a quad cam and the other is twin cam.. and if its possible to do so anyone know how i can get a hold of 2 heads to be grafted to a 500SE-w126 .. thanks
