big bore 'crush type' exhaust gasket

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 ?

Thanks in advance

Any idea of the dimensions? There must be loads on ebay?

Do you mean the manifold to engine gasket or the donut gasket to the cat?

My 2bular supplied engine gasket blew like a trooper and was nowhere near the right size for the notes, but a legit toyota one fits and seals perfect.

I’m also on the hunt for a donut gasket for when the car goes back together but I was half sure it was the same size as oem needed?

It’s defo the exhaust manifold gasket, h111 said the std one was blowing, so they need one that fits a 2bular manifold… the opposite to you then !

I would take H111’s word over mine!

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.
