I have been wondering about are Heads for the 5.3. Does anyone have any experience with this? Will heads help, with my setup?

I have searched these forums and have found some decent information, but I wanted to get a final opinion on this from the truck guys.

 

The stock 6.0L heads are the most common setup. You can find them pretty cheap ($300-$500) and if you are friendly with a machine shop they can clean them up a tad and that's about all you really need. This will drop your compression to about 8.6:1 or 8.7:1 depending on what gaskets you use.

 

You can spent $1200-$1800 for a nice set of heads.A better option would be a good clean 5.7 0r 6.0 longblock.Better bang for the buck if power is what you are after.

 

Good stuff.

What difference would a combo of heads and intake make?

And what intake would u recommend for the 6.0L heads?
