When doing a BOB Cosworth conversion, I realized you can’t buy the gaskets to match to the BOB exhaust manifold flanges, so I decided to draw them up in CAD and get a batch made.
They are made from 2mm high quality exhaust gasket material
CNC laser cut flanges to suit these gaskets are available below!

£42.50 for the pair, posted within UK!
Please note - the flanges shown in the images are NOT included, only the gaskets.
