@ace_098 does it happen to be your camshaft discussion here? I've just ordered the 268 from dBilas myself due the higher lift compared to Schrick, and trying to see if the difference in lobe separation (aka Spreizung) is a concern or not. https://www.motor-talk.de/forum/268...chrick-nockenwelle-hilfe-t3904770.html?page=1
Sorry for not answering in a long time, had some time off. As for the cam, I am fairly new to the whole VW stuff so I really can't tell much that would be useful.
LCA differences in a 8V motor with a combustion chamber is not going to be a mechanical issue, as you have plenty of piston-valve clearance at TDC. If I have understood the question.. LOL Jon
