I have a 2bular manifold (its at least 8 years old) - So as part of my engine rebuild, Hangar 111 used a Lotus/Toyota gasket, originally, but with the issues with the replacement block, they also noticed that the std gasket was blowing a bit, so are asking me to get hold of a larger bore one - I will go directly to Jim if needed, but anyone know where I could get one ?
Obviously things change a lot over time, I know the 2bular stuff has gone through many iterations over the years so perhaps the situations are not comparable.
