one thing i have noticed is how restrictive the intake manifold is especially the plastic upper section, i had a search but there were no custom made ones and you cant really port plastic

Friction plate.
Port and polish is recomended by me .

Also Do a port match exhaust side using a genuine fiat gasket .
