Default port and polish or new heads?

What would be the best route to go? Should I get ls6 heads or a port and polish on my ls1? Which should I do and which would get me more hp?

If its within your budget then buy new ones. After your done porting and polishing them you will have dam near broke even on a new set

buy LS6's and port/polish them
unless ur planning on going FI/Juice then aftermarket since they have thicker walls better for high psi
