timing chain set questions

alright so i went around hunting down a timming set for my motor so i could finnaly get it in the car.but i have a few concerns and ?'s about it

first off this is going in a 3.1L 60 degree chevy v6. motor is of course turbocharged

now the factory gears are cast iron, this is what i was expecting to get in the new timing set. wlel i get home open the box and these gears look liek galvanized steel, so im assuming these are made out of the pressed metal stuff they make the spider gears for rear ends out of.now is this stuff any good or should i kepe the factory cast iron gears, which theres nothing wrong with.

second crank gear looks to be poorly machine it has a nice burr on it were the crank hole was bored, i should say looks to be more of drilled, the hole is not smooth at all, i know the burr has to come off,but what about the bore not being smooth should i polish it out real lightly with a fine drum on a die grinder??.Or once again should i just stick with the factory cast iron gears.
the cears in the set are deff not cast gears

last ? is if these new gears are fine is would lightning the cam gear do anything or is it just a waste of time, and would it weaken the gear..

heres a few pics of the set minus the chain. to me the chain in the set is the only thing that looks decent.

Is this a parts store replacement set? It sure looks like one. Being its turbocharged, I would bite the bullet and call the aftermarket, like summit or Jegs to see if they carry anything for it as I would think they would. I wouldnt even trust a stock replacement set on a super budget beater engine, but thats just me.

comp cams makes a dbl roller chain, and a billet gear/ sprocket set, these have been discontinued as far as i was told,and have not been able to track one down. as far as the stock stuff goes i know of only one person who has ever broke a stock cam sprocket, and that was on a massivley nitrous injected 3.4 which is the same motor just a larger bore. the sprocket literally broke into 2 pieces. it was never figured out what caused this.

so im pretty much stuck with stock replacements, though i have thought about having a custom gear drive made, but i dont want the noise the turbo is deff loud enough all on its own.

so my only 2 options i believe are the stock cast iron gears, or these what apear to be pressed metal gears

In this case I agree with DoubleVision you get what you pay for, and do some other searching around for a better set. In this case I would call Summit and talk to someone and explain what you have to see what options they have available.

Just to update you, I did a search on Summits website and found they carry 3 sets, all made by Cloyes.
