How specifically do you match inlets?

[mattfarina]

The sister company of the place I work is a metal machine shop.

If I was to ask them to match my inlets, how specifically would I ask them to do it? Is it an easy enough operation for a skilled machine shop?

Easiest option is to "match" them to the line of the gasket.

match them to 0.5mm off the gasket line, got mine done to this and mine worked a treat

I thought they polished inside aswell? Have they just rounded the edges off and lined up the gasket?

looks that way to me.

I think it all depends on the ID to begin with.... Dependant on the quality of the OE Inlets depends on how much you take off as far as I can tell from researching.

thanks for the replies, anything they need to be wary of when machining?
