Inlet Manifold Port Matching K4M?

[AS_BO]

What do we reckon to this? Copied and pasted from CS.net.

Looking to some Renault guru's for a bit of knowledge here. I know you Clio lads port and match inlet manifolds on the F4R but does anyone know whether or not the castings for the K4M manifold are prone to the same gash casting marks/imperfections and if it would be worth doing on my Twingo? I'm not chasing BHP here, just response and to satisfy my curiosity

My lower Iinlet was a poor match to the head ports. Back on page 1or 2, I had the TB and upper manifold off. Theres definitely room for improvement.

Scrap that, just read it. So it's just a case of take the measurements and work through it? What grade did you finish up with?
