Deck height, What went wrong? Options

[DavidSweden]

I am rebuilding my 2.0 engine

This evening I installed #4 cylinder & piston (with new rings). I then tightened the cylinder down onto the case to measure the deck height.
The deck height came to 0.2mm which is 0.008". as I understand it the deck height should be about 1mm (0.04").
I have installed new crank bearings, the piston and cylinder are original, the shim under the cylinder is the same thickness as the original shim.

The deck height should be the same as before the rebuild shouldn't it? Anyhow the deck height seem very small.

Advice appreciated

The deck height minimum is to prevent the piston from ever hitting the cylinder head. The pistons rock in the bore and the rods stretch at high rpm.
A stock cam won't cause valves to hit pistons even with no deck height.

I say just get a set of barrel spacers that gives you the deck height you used to have and continue assembling.

Thanks to everyone for the help

I have CC´d the heads and get about 60 CC´s, the piston are the US stock type and the dish cc was 5 giving a total of 65 cc or there abouts.
I remeasured the deck and with a lot of care its about 0.015"

I will be installing a head gasket, the gasket measured 0.028" but I guess it will lose some thickness when its crushed?

I am running a stock cam. so working on the info from Chris that the piston will never hit the valves I should be ok..... or have I misunderstood something?

Using the above data I will have a compression ratio of 7.7

If I put the head on with some clay on the piston as suggested by Stugray and tighten down the head is it ok to then reuse the head gasket after its been crushed?

Will I be ok?
