Congrats on snagging that kit!
I had a similar setup a few years ago. 65 Polini, 17mm Amal carb, and Polini pipe (chamber dimensions were Biturbo-ish) on my Avanti. The Polini pipe for the VIP is very hard to find. However, that's not such a bad thing, as that pipe is very one dimensional. It has a a really short header, which absolutely kills low end (even with a 2 speed).
