Default Built motor.. first startup knock.

So I have built EJ257 with Eagle rods, Wiseco pistons and Cothworth Crank bearings with 2.0 WRX heads. I stardet the car up few days ago and it started knocking right away. I have no idea what could of went wrong. Some people tell me its the rod bearings, I have no clue how could that get messed up, but other people tell me that it could be the Wiseco pistons, they say Wiseco pistons dont fit well and it could be really bad piston slap that I'm hearing.

If anyone knows what could be wrong or give me some advice please do. It took me alot of time and money to do this the right way and it seems like it was all for nothing.
