All of OUR newest headers are being made with a 15MM thick top plate flange where it bolts to the side of the cylinder head instead of a 1/2 inch or a 3/8 inch flange with ugly spacers often found on older design headers.
Our headers are consistent with the thickness of the intake manifold thickness and the surface is machine ground on both sides for flatness.The thicker flange also affords greater rigidity and cosmetic cleanliness.

It is suggested that 1600 owners use the short U20 starter or the short gear reduction unit with the headers as there is less clearance between the header pipe and the end of the 1600 starter.

All our starters work with original manifolds and headers.
