Technical Can I use the gasket again?

[mechtech]

Hi fox, today I made a terrible rookie mistake.

I have a punto s60 2000.
When I installed my skimmed cylinder head, I don't realized that when I disassembled the old head, one of the 2 guide pins in the cylinder came out with the head (I just noticed that now when i looked on the pictures that I took when I disassembled the head.

Now, I'm pretty sure that I put the gasket align with the holes and also in the right side, but with one pin only (the one that close to the ECU Temp Sensor).

My questions is, can I use the gasket again?
Are the head bolts wont snap in the second use (I'm using Haynes and a torque-meter)?
I already started the engine for 5 minutes.

Thank you in advance.

i think it should be all aligned up, the bolts would have kept it inline so i think it should be okay as it is.

i dont think you can use the gasket/bolts again as its already been tighted so will have been compress/stretched
