Drop in kit is springs/retainers?
Like the small stem conversion, who can the guides be purchased through (2.02/1.6 for Dart)
Those heads and seats are horrible from the factory!

Lot of good information and some dyno match ups for various TPI components here:
Just a lot of good, general background links and information too. It's a good read.

Very nice.. What tools are you using to finish that? Carbide cutters and sanding rolls?
I've got a plenum and some runner that I'm going to port match and smooth out, and I want it to look exactly like yours when it is done.

Some damn good numbers. How is the velocity on those ports if you mind my asking?
