First off, most smog laws suck. I left Cali for a number of reasons but unfare smog tests was number three.
If it passed the test last year (and we are assuming they didn't just hook it up to a different car), then it could be the timing belt, timing, valve clearance, carb, vaccuum hoses, pcv valve, gosh the list is a longer one than this.
I say, consider it another tax of California, and bribe the smog tech. Or, remove the heat shield off the manifold, and wrap the pipes with header tape, all the way to the cat. Then put the heat shield back on. The strategy is to get the pipes so hot before the test, that they will act as another place to burn the fuel. I wouldn't drive all day that way, but...
