Heads and New Base????
I was wondering if anyone could tell me if a new base such as edelbrock or any other company would fit to Dart Pro 1 Aluminum heads?

As long as the port sizes on those Darts isn't so huge that it requires a 1206 gasket, any stock or aftermarket base will bolt up (vortec stuff not withstanding). You just need to make sure you get the early style base, because the later ones will have the center bolt holes at the wrong angle.

I wanna saay the darts are 64cc and 200cc. What do you mean by the older style ones? I want a new one that is larger then stock.

in 87 the bolt angle for the center 4 intake manifold bolts changed. I doubt the Darts use the new angle, so you need an early style TPI manifold, which everybody produces anyway.
But if the Darts are only 200cc, they should mate pretty well to a 1204 or 1205 with minimal work, so you should be able to use any aftermarket TPI base... TPIS, Edelbrock, AS&M, Accel, etc..
