I need a new head gasket and was thinking about buying the one from dezod but it has a option of a 89mm bore or 90mm......the stock bore is 88.5mm so is it ok to get the 89mm?? or should i just go and get an OEM one?

get OEM from TRD sparks. i've heard some bad things about the cometic head gasket.

 

Reliable sources? Like what? I know several people with these without issues. Also who did the assembly of the engine? Its easy to blame a faulty components when you don't know 100% what you are doing even though you might think you do.

To me building an engine isn't assembling it. It involves machining the head, machining the crank, machining the sleeves and etc. Assembling the engine involves a lot of checking i.e. runout, tolerances, using plasti gauge and etc. Using new bolts instead of trying to be cheap and reusing head bolts (most not all head bolts are torque to yield meaning one time use and you will never gain the proper torque again). Properly assembling components using the correct torque and following the torque procedures.
