Hi,
The 885 head on my 2.5 has cracked and i have a 731 head hanging around but it's from a 2.0.
Would I be able to fit the 731 head without any problems (apart from slight power loss!)??
If not if anyone has a cheap head that will work for sale let me know!
Cheers jamie.
Can a 885 head be replaced by a 731

No the head won't fit as the 325i pistons stick above the block and the 320i ones don't. So the pistons will hit the 731 head.
I have rebuilt heads, they are cheap, for a rebuilt head, but not cheap compared to a worn out head for £100 in need of a rebuild
PM me if you are interested.

Without modifying the head no, replace an 885 with an 885 and a 731 with a 731.
However Byron that 731 test head i have used to live on a high comp b25 bottom end.

My next stroker build I want to do I am going to use a 731 head, so I can run flat-top pistons and get the compression right up. Just trying to find a 731 head here in Aus is a bit a of a challenge unless I buy a whole motor which i don't have room for...
