And where can i get its head gasket? How much it will cost to replace the head gasket?

Looks like a 4efe.
You can read the engine name it's written between the exhaust manifold and radiator hose.
You can buy a oem gasket from any toyota parts shop.

E series engine. 4EFE or 5EFE.
Gaskit easily available at any Toyota parts store.
If its only gaskit than should be around 4k to 5k. In case some head work needed than expect more.
