I'm sure others have more useful advice, but the one thing I know from my air cooled days is that deck height is critical for the proper compression ratio. If you lap them in, you may need to raise the deck height using shims between the jugs and the case. An experienced VW machinist should know what to do, but that would not be anyone under 50. Probably 60.

I burned up a 1600 engine by not paying attention to this years ago, but maybe the 2.0 is more forgiving.

So I've got my heads off to do a top end rebuild on my 81 2.0 air cooled. What's the general consensus on using the jug/head gasket/crush washer? Or just lap the jug into the head? They are at the machine shop getting a look at. Which way should I go? I've read Bently and have gotten mixed results from everyone!
