H.T.S.R. HEAD (High Turbolence Squish Racing) Heads with high turbolence concentric combustion chamber, squish set during the dynamometrical brake adjusting, re-calculated linings and cooling surfaces, made of high silicon content aluminium, pressure melted, worked on highest precision working centres, with anti-detonating and anti-oxidationtreatment on the surface.
