94 K1500 TBI / Vortec head swap - Cam question

[Fast355]

I only mentioned idle because several current descriptions of the cam include "idles smooth."

Here is how the 395 cam idles at 600 rpm with ~16° timing advance more timing made it idle even rougher. At 750 rpm it likes 22° of timing and pulls down to about 40 kpa.
