what is "porting headers"
I saw this being mentioned alot but what exactly is done the the OEM manifold?
How much work is involved, what is being done and how cheap/or expensive is it compared to just buying a new one?
I could get a brandnew Fujitsubo manifold for 620 GBP including shipping from Japan which seems more a piece of art than the HKS one and also weight "only 6 kg". How much would I be looking at for porting the OE header?
