Let me preface: I'm not a mechanic and I've never built an engine, so what I'm sharing below is secondhand from my engine builder...

We are in the midst of building my stock 2.0 into a 2056. I purchased 96mm Pistons & Cylinders from European Motorworks, along with new valves, cam, and various other hardware... EMW also cleaned/refurbished the heads and rods.

My engine builder here in Virginia is a little bewildered by some of what EMW sold me. Specifically, he says that the alignment of the rockers & valves "sucks". The valve adjustment screw has to be turned all the way in, buried in the rocker, and it still looks like there will be severe wear. He suggested we might have the wrong lifters or need longer pushrods. Or there might be an alternative to use rockers from a 1.7 and/or something off a 911 with a ball & socket joint.

I'm going to post the full invoice of what I bought from EMW -- perhaps someone can help me understand the issue, either from the notes above or by reviewing the parts list.

Does this make sense or sound familiar to anyone? What's the right fix? I'm stuck in the middle of trying to get resolution from EMW for an issue I don't fully understand, but I want to see if anyone here might quickly spot the problem.

Yep. Cabinetmaker nailed it.
EMW did not do it without you asking for it as the cost is vastly different.
Part 054-624 (911 adjusters) are $17 a pop. But you need them.

The 1.7 rockers you may need to source. I don't seem them on the EMW website.
You may also need new rocker studs.

Your best bet is to just call EMW, talk with one of their techs on the phone and have them help you gather the stuff you need. They are excellent.

And, again, get the chromo push rods too.
