I searched and searched and couldn't find the answer I was looking for, so hope this hasn't been covered, but here goes. I'm probably going to end up buying a DC4 that I've been looking at. It has a B20B with a VTEC head. It's a black valve cover, and the guy says it's off a B18C1. So here are my questions:

1)Is there any way to tell for sure if it's the GSR head? I assume it is since a B16A head would have a red valve cover, and I believe those are the most common VTEC head swaps, correct?

2)How reliable is this set-up going to be?

3)About how much power does a B20B/VTEC typically make? It's also got a CAI, Headers and CBE.

Any answers are much appreciated, thank you.
