I can help with some of your questions. You have to replace the
speedometer assembly to fix a broken odometer, and you can find used
speedos for about $60-70. Replacement is easy for the backyard mechanic,
and it takes about an hour. Get the old speedo out (or talk to a
knowledgeable shop) to make sure you get a replacement unit for your rear
The 1979 and earlier big-6 cylinder heads had a tendency to crack,
especially in the 530i with thermal reactors (lots of heat under the hood!)
That is probably why you have a later head. This should not give you any
problems, as long as the head matches your cylinder bore.
I converted by '79 528i from a 4-speed to a 5-speed. Basically, you need
to find a used Getrag 265 tranny. Here is a quote from a 2-year-old post

You will also need a driveshaft, flywheel, clutch assembly, clutch master
cylinder and pedal, hydraulic line, slave cylinder, throwout bearing, etc.
And last but not least, you need to replace the rear mounting bracket for
the transmission. 5-speed trannys have a different bracket than the
4-speed or automatic. I found my trans for $950, with bracket and
driveshaft, and with 100K miles on the parts. I got lucky. You will need
to hunt around a bit to find a 5-speed.
One alternative is to look for a decent 528i with a 5-speed. Someone just
listed one for less than $1000 (with a noisy transmission); typical asking
prices are $3000-3500. This will give you a car that has a catalytic
converter instead of thermal reactors, improved cooling system, and
electronic ignition. 530i's tend to have cooling problems, although your
new cylinder head eliminates one potential trouble spot.
