It could be just a bad camshaft or a bent valve. But if it is the piston, I would rebuild the whole thing. depending on where your from it can be any wheres from 600 to over a 1000 to have it done. A used engine can run from 275 and up. I build an eclipse for 500.

Shoot yeah, it's expensive to fix. If you're lucky it could be a burned/bent valve and the repairs will be just in the cylinder head- $2000. If a piston is burned from that freeway drag race you won last Friday night, the engine will need more extensive repair. Double the cost. If you're so lucky as to only have a blown head gasket, get that fixed and buy a lotto ticket which will win. Stick a new cam belt on it too.

Expect to spend at least $1000 minimum to fix it. It could be in the head, in which case the head will need rebuilt, and that's about $1000 plus the labor to remove and reinstall (and they might as well use a new timing belt and water pump while they are in there...add another $350-500). It could be the piston itself, in which case the engine needs to be honed and rebuilt with new pistons, rings, etc. That's, again, about $1000 in labor plus parts...Figure about $2000 or more for that.
