I pulled the manifolds off the 4K this morning and found they are leaking between the exhaust ports. (surprise surprise.. piece of shit design!)

Anyway, the only manifold gasket from ACL is a two-piece one, just like the leaky pair that came off. Repco & Supercheap & Auto-one & Autobarn all seem to stock ACL gaskets now.

The one-piece ones exist, they come with the full headset for over $100 !

Does anyone know where I can buy a one-piece gasket by itself?
