78 ironhead head gasket???

[Truco]

Hi, I am ready to mount the heads on my 78 ironhead, but the problem is that I can find the gasket: the gasket that was on the bike is a copper 0.045, the only ones I can find are 0.012, maybe a 0.016.
My question, is any problem if I put the 0.016 instead of the 0.045????.
Thank you guys!!!

No problem at all. Yes, by all means use the thin gasket!

The thick gasket was used to lower the compression (on an already relatively low compression motor) back when the gas available was really shitty.
