Definately worth putting 325i valves in and getting the port throats cut out to match, I've done this on 2 of my 2.7 conversions and it makes a hell of a difference.

Figure on about Ԛ£200 for the machining work.

Couple this with a zone 2.7 chip and a decent cam (272 degrees or so) and it'll really sing.

Cheers,
