There's a few that make 102mm gaskets but don't know about 103mm you might have to get a custom one made

I have seen cometic have 103mm in 1.52mm thickness ,
This block have liners that have dropped a bit and there is allready 1.6mm gaskets in it , so i need 1.6mm thickness maybe more depending on what needs to be removed to get it flat again

That is not how I would approach this problem. How much did they drop, and when they did did they shift or rotate any?

If it's not much I would be more inclined to deck the block back to flat.

The problem i have with this engine , new build in the US , shipped to Denmark ,
I have only installed the engine , had it startet to heat it up , brake-in the the lot , all new parts

Sounds great when running , i turn it of , then i Will change oil and filter as i always to after the first heat cycle ,
The first thing that comes out if the oilpan is collant , then the oil
When drained , i let it sit 15min and the loosen the drain plug and again coolent comes out , so engine out again ,
I have the engine split , and have sent the blokhalves and heads to a machineshop to pressuretest it , and all 4 darton sleeves are leaking when they are pressuretestet ,
So i Will try to see if i Can remove the liners again , reseal Them and install again

But dont know if its possible
Also there is No pistonguide holes i the liners and its a pain to take apart an assemple again ,
The crank is 82mm
Does it matter that the pistons goes deep into the holes ?
If its not a problem i Will have the holes made when the liners are installed again

I'd machine the deck, O-ring the flange, and order up a new set of Cometics.

Then compensate camshafts for the adjusted timing.
