I just had my 2.2L motor rebuilt. It started out as a 2.2T, but I have installed S pistons and E camshafts. I thought all E camshafts were the same...I now learn that there are two different types of E cams.

My question is...how can you tell the difference between the two types of E cams

Here are the left and right numbers on my cams.
901 105 181 00
901 105 110 05

I would have thought that the above numbers should indicate early E cams.

How can you tell??

Thanks
