Update: the measured ID of the OE manifolds (headers) on my 2009 V8V is about 72mm (2.83"). This means that neither conventional 2 3/4" (70 mm), nor 2 13/16" (71.4mm), ID gaskets will be the best choice. If you choose not to use the factory Aston gaskets, the best options I found are based on a 3" (76.2 mm) ID. Offerings from Vibrant (pn 1463) and Ticon have the correct bolt circle, flame rings, and appear to be well built. The unbranded gaskets I received from Velocity AP were 3" ID too btw, and looked just the Vibrant ones.
