A few questions about stroker small blocks

Thanks for all the comments. Every time I get to thinking I am pretty knowledgeable, I hear from my FABO buddies, and I realize how little I really know. From what I am reading, it sounds like some Eddy heads with a little work on a 340 might be the way to go. I have J heads with 2.02 valves now. Are they worth spending 'porting' money on? I have read a lot about W2 heads, but that would mean new headers and intake, right?
W2 heads require specific intake, rockers, exhaust. It is a large initial investment but they do perform.
