throttle body needed?

[badbird]

If I port my stock intake and heads, gasket match the runners and port the throttle body holes to 58mm. should I get a aftermarket 58mm throttle body?

The block is stock, it has bbk headers and y-pipe, no cats and finished with a flowmaster. I will have 1.6 roller rockers. soon as well.

thanks

i would port the TB bore to accept the 58mm but would not put one on a stock motor.......52 would be the max for a nice bolt on car
