Check! Good luck!

Thanks!

Some other questions:
Should I use a similar head gasket as the one I removed from the engine with this "new" head?

Should I swap the camshaft with the one from the cracked head?
The end of the camshaft in the new head is similar to the old one with the two tabs.
There are probably some differences in cam lift or duration?
Other factors to consider?
I have installed an electric fuel pump.

We don’t recommend early heads. And would only repair one on a Csl or Csi.

just look at yours to understand why.

look for a later head but not after 1986.

@sfdon , what's up with heads that are newer than 1986? Inferior / less ideal because...?

I have one dated 1987 on my car...

Dismantled all the pieces of the old head today for learning purposes. Found that almost all of the valve stem seals were brittle and would fall apart easily. On the intake side I could just pull them off with my fingers.

Also took a closer look at the pistons and found the same marks on top of all of them at the same spot.

Got me thinking if there has been some timing issues and that the exhaust valves were hitting the piston’s?

...all of them at the same position.
Guess you are are right, a timing issue!

If you install the new valve stem seals without protection against the sharp edges of the stem (valve stem keeper) the new rubber seal will be scratched/damaged!! It ain’t much but the seal is damaged!! Oil consumption will follow.
So:
Sometimes in the new seal package there is a plastic cover.
Otherwise you can use a simple method which I “engineered” - by putting some plastic tape over the stem before sliding the seal. I made a picture of it.
Good luck

1987 is different head on e24 m30b35 everywhere
1987 head in Europe on e32 is m30 b35

Casting date is not engine design date.
Everything is different in Europe- all your engines came a year before ours.
