Anyone know the size of stock intake ports?

[Nicad]

Have my carbs off and noticed my ports look altered and larger than ones I recently saw on a 2800.
Did earlier heads have different sized ports?

I can measure them later today
Thanks.

They were probably port matched by Korman or whoever did your engine work.

I am pretty sure the ports on earlier versions of the M30 were smaller. I do not have the original head on my engine, and when I bought my first round of intake gaskets that were appropriate for a 1972 engine, they were smaller.

The measurements are on m535i.org. I posted a link in the "is it an m90" thread in the general section.
