2056 Valvetrain question Options

[flipb]

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.

I agree with Stugray.
Either the stock pushrods are not fully seated in the lifters and/or rockers, or the base circle of the new cam is way larger that the cam it is replacing.
Stock 2.0 rockers and adjusters should easily fit right in there, and setting proper geometry only requires some shimming at the base of the rocker shafts.
1.7 rockers, 911 adjusters and chromolly pushrods are not a requirement of cam replacement, but it is the preferential way to go since the 911 adjusters, if set up properly, will greatly reduce wear on the valve tip and valve guides.
Ask your builder to call Jorge at EMW, he's a good guy and will help him troubleshoot whatever is going wrong there.
