Quick Questions (E30)

Hey

Just a few lil' questions that have been bothering me over the last couple of days.

1) Is there any difference between the 320i and 323i head (except the cam, I think the 323i is 260/260). I know there both 731's, but does the 323i head have bigger valve ports?

2) Is there any difference between the Fuel Pressure Regulators in the 320i and the 325i?

I think there is, But does it mean anything? (say, if your going to 2.7ltr)

Thats all for now, but be sure there will be more to come.

Thanks

Antony.

Factory operating systems from the Bible as flows:

L-jet M10B18 and Montronic 1.1 all FL325i's are the same at system fuel pressure of 3 bar/reg pressure 2.8-3.2 bar. Where 84 to 87(some) 325 run at a lower 2.5 bar/reg pressure 2.3-2.7bar.
