Yeah, I also bought some of those inexpensive (compared to new origonal ones) aftermarket rocker arm shafts off ebay a few years ago. When I found they were undersized I called the place I bought them from and they took them back and gave me a full refund no problem. I just had to pay shipping both ways.

Then I bought new origonal ones and what a difference in quality, machining, and the polished finish... no comparison at all.
Those cheap aftermarket ones can also crack at the groove where they expand if and when you tighten the crap out of them trying to expand them to lock them in place.

Those aftermarket rocker shafts are no good. They are around .0001" undersize in diameter so they don't lock into the holes for them in the cam tower and they will leak oil.

Use origonal porsche rocker shafts and rocker arms.
