Trick Flow Heads?

Got a line on a local guy selling some Trick Flow Heads for a small block Chevy. Complete Series 1 Twisted Wedge aluminum heads. Any experience with these particular ones?

I believe they were pretty decent performing heads. The canted valves are unique. I believe they had issues with guides wearing out and needed a special valve train?
