Head and Paint!

sup all
I got two questions.

1) Has anyone gotten their car painted at Maaco or another national business? If so can you tell me how it looks, what kinda paint job u get and HOW MUCH was it?

2)Secondly, I hav a question about a Head swap. If i hav an LS motor (B18B) and i want to do a Type-R or GS-R Head Swap, can i just buy the head or do i need internal stuff like pistons and valves or crap like that?

THANX ALL!
