Ok i did a search and there wasnt any results. I know that your suppose to take out theoil jet in the block when you do a mini me but where is the oil jet in the ex head?? you see it cuz i cant see.

 

It's in a completely different location on the head, and it's a totally different style.

I don't know exactly where it is though... On my Y8 head, I couldn't find any oil jets, and the Z6 block didn't have one in the spot that my A6 block has....

So, just worry about taking off the oil jet from the A6 block.
