AAN exhaust manifold will bolt up to a 7A head, ports are the same size. Bear in mind though, 7A head only has 2 studs per exhaust port, unlike S2/4/6 multi stud option. The casting is the same, but I would have the 7A head suitably drilled and tapped to take the additional studs, as the S2 / S4 / S6 manifolds are prone to warping at the best of times... 7A head doesn't have means of attaching Hall sender as on ABY / AAN / ADU engines...

I've already got my dibs on a 7A head that is hiding at a secret location in Belgium. Its for development - hoping to be ported and as shiny as MarkH's wonderful looking item. I already know that I need to create holes on the 7A head for the camshaft mounted hall sensor (CMP) - but have you seen it done before - I just wanna know that I won't be first in that regard.Originally posted by Vagsport
Trouble with using a 7A for this, is that I need to replace all exhaust valves with the Sodium filled items of the S2 engines. Mucho $$$
