Hi my ports in my heads are much bigger than the Cobra inlet I have. Is there anyone that can ExtrudeHone as that company does so well in the states? Atleast port them? At what cost etc.. Thanks

That step change you are referring to is a key point of modification by Tickford on the 220 engines. Makes a huge difference in flow to match port the intake. You can do it yourself if you know how to set up the gasket for drawing the outlines.

I had someone else do it for me when they did the heads!

Try calling COME engines in Melb. They do a 'powerport' manifold for Holdens and they may be able to do a Ford one, too. Also try Harrop engineering. Don't have ph numbers, sorry
