Basically, you want the exhaust valve closed when the intake valve opens...

If I do the conversion then I don't have to worry about all that right? Just get a cam that I know works and put it in.

No way. I'm not gonna spend money on headers when I already have some. I LOVE the sound of these.
Ya, I have 1 3/4 and it may actually be good so as to not lose as much boost when I cam it. It would seem anyway.

Ya, I have to do some more reading. But, again, if I just pull the heads, It becomes much easier.
