I believe the diagram for the Maniflow heat shield posted by Ken Plumstead shows incorrect dimensions with regard to the centres. It shows centres of 21 cm. I bolted my Maniflows to a spare stock intake manifold, so that the head ends were together. This should give the correct carb spacing at the carb end of the Maniflows. I then measured centres of 20 cm. This also puts out some of the other dimensions. Apart from that it seems like a good design and I plan to use it with suitable corrections.
