Do you mean the engine SOUNDS noisy, or that it RUNS rough?

wow i hope your not from an english speaking country. well if its not running smoothly go through all the normal checks, compression first to make sure everything is good. basically start over and try to locate whats bad. some more info would have helped a lot more.

.003 or .0035 would have been my choice.

.003-.0035 is a bad idea for 400 whp. All the big power boys are running .006+ with years reliability.

.003-.0035 is too tight? my SRPs recommend .002-.0025....is that no good?
