Yeah! Not you sure did you say huh there is not sense too much making in the if ask me you did. In any case, here's some advice:

TB - remove hump just before throttle plate and polish everything else
Upper mani - gasket match ports on runners
Lower mani - gasket match ports on upper runners, carefully knife edge humps under injectors and blend back into runners for biggest gains.

Try to speak a little better than an 8th grader fresh off the boat in the future. It's easier to understand you when you write in a semblance of English.

what ^^^^^^^^ he said!

Send it to someone that knows what they're doing.
