You should know that they won't make any difference on a stock or stockish motor, other than making your throttle more sensitive on the low end.
I bored mine myself using a boring bar, to 2.09", then radiused the inlets, raised the "towers", and removed the "swirl plates". This was on a modified 400. On a stockish 350, bored TB's won't do anything.
You can sleave then to go larger than I did. "Dan the boring man" Plette (I think is the spelling) does them.
