Port maching or not?

Hi, i have a doubt, should i match the intake entrance of the cylinder head with the manifold?

You can remove quite a lot of material from the inlet manifold to try and make the engine breathe better.

I had the inlet manifold done on my Clio. You won't see much of a power improvement though, if any, as it is so difficult to squeeze extra power out of a F4R engine. But every little bit helps.

I got my inlet manifold done by a company called MS Custom Engineering.

Puedes quitar una gran cantidad de material del colector de admisión para intentar que el motor respire mejor.

Me cambiaron el colector de admisión de mi Clio. Sin embargo, no notarás mucha mejora de potencia, o ninguna, ya que es muy difícil sacarle más potencia a un motor F4R. Pero todo ayuda.

Me repararon el colector de admisión una empresa llamada MS Custom Engineering.

I have done the same but mu thread is about the cylinder head, the manifold exit port that is linked to cylinder head is bigger.
