Weber 48IDA help

I just bought a Weber 48IDA, i need some help on the jets and venturies size. The engine is a rebuilt stock GSL-SE 13B 6-port.

Here is the recommend sizes from Racing Beat, I don't know if they are the right choices.

Venturi - 40mm
Fuel Jet - 195
Air Jet - 205
Emulsion Tube - F-4
Needle Valve - 250

Also, where is the cheapest place to buy these parts?

The cheapest price I found right now is this one... http://www.carburetion.com/Weber/weber.htm

It's not the same engine, thanks for being smart, though.

F-4 emulsion tubes? I guess the extra 2 ports like them but for what reason?

I'm running a 6port street port and I put plenty of jet info in that thread so it was the same engine. In my tuning I've found that there are very little changes between 13b's in tuning.

Dude...call or order the #300 from racetep.....why would you want to go smaller if larger is available?

...the place is about 5 miles from my house....if you want, I'll pick one up for you and FedEx the ******!...sheesh.
