You can use the newer heads but a simple modification is needed. I might add that hundreds of people have used newer heads on the A12, so it is very common.

Quote:
I have seen a crude system where a 1200 head gasket was placed on the head to determine the position of the oil feed hole in the block.
This was centerpunched & a very shallow hole was drilled. [about 1 to 1.5mm] then an angle grinder was used to grind a small trench across the gasket face to provide an oil passage froom this shallow hole to the nearest head bolt hole.

Crude as hell, but it worked. A very steady hand would be a prerequisite.
Personally, I would suggest a milling machine if this method is used.

Read about it here: Tech: Head oil passage, especially click the link to the Discussion.
