Need head identification help.
 
I need help identifying these brand new spare heads my friend has, part numbers are RF2W936C064 and IF432D. Here is the story, purchased my 03 late year s type 4.2 with a bad drivers O2 sensor several months ago. Noticed a rough idle on start up and hard to start after driving awhile. Never saw heat deviate from a hair over half on the temp gauge the entire time I have owned the car. Got a low coolant light on the way home and pulled into the closest autoparts stores to get some coolant. Upon opening the cap I found the evil chocolate milk, oil in coolant. however no coolant in the oil. I believe it to be the drives headgasket and or head. I'm guessing the this issue is what caused the O2 sensor to go out and also explains why my friend who sold me the car was experiencing surging. if the heads listed above are for my 4.2 I will buy them from my other friend and use them to make my car right again. My $5000 car is about to get expensive.

No luck. Is there any way to tell between the 4.0 and 4.2 heads?

Maybe ask Jaguar (not a franchise) themselves? Or someone who'd work (perform machining) on them.

Message Avos or Brutal. They would know if any distinct similarities/disimilarities.
