We fitted some MSDS headers for Mr Brown in Tx when we did his Quaife.Have to say that the headers,not just MSDS,but any that have a 'one piece' port flange need to be modded if you want to avoid gasket leaks at the head.If you look at the stoc manifolds you will notice two things, 1)each port flange is a 'single',due to them being 'cut' 2)at each end is an oval stud hole.Both these were added because without them the flange cannot 'move' against the head (coeff of expansion of steel Vs ally),this causes the gasket to blow in time .I'd advise that the one piece flages are cut in the same place as the stoc manifolds and the hole in the 'oval' location opened out.Regards Terry Haines,HMS Inc
