Where is the bes place or site to buy engine???

[bunso]

from those pictures you could just put in new valves, and put the head back on.

unless I'm missing something?

Everything you see is all of it. Nothing wrong with the engine till timing belt broke.
What do you think of this Cylinder Head from Ebay
GM CHEVY AVEO 1.6 DOHC CYLINDER HEAD VALS&SPRINGS ONLY | eBay
Or should I just rebuilt my Cylinder Head and is there any detail how to for it?

Thank you,
