Alpina M20 2.7 Head Verification

Post Mon Jul 17, 2006 3:35 am

How can you tell the if a head is a real Alpina M20 B3 2.7 Head? Are there any numbers or identification to look out for?
I've seen a head for sale at the wreckers who claim its an Alpina head but it may just be a worked head.

Cheers

If it's genuine Alpina, it will have four digits stamped into it near the front, inlet side. Simple as.

Later cars have Five.

The numbers are just above to the right of the thermostat housing, vertically stamped on a raised part of the head.
