Federal LB7 heads have different intake runner design than the Cali heads. Supposedly the Cali heads flow less. I've never had any trouble with the Cali heads, so unless you need to pull the heads for some other reason, I would leave them.
Picked up this gem for a steal. #4 has a piston issue but the truck is super clean. 04 Cali Lb7. Haven't decided if I'm going to lly swap or go federal lb7 with SAC injectors.
Anyone know the difference from federal to cali heads?

Maybe. You might have a better single battery than me. Mines just an interstate.
Looked at it hard, thinking of having the ELF mod done to it for future wheel tire combo
What air filter do you run? I'm looking for something that does a bit better than my current aFe 24-91039.checked front end over, found pitman arm nut backed off (second time it did this to me), tighten it up, everything else was good. Checked engine and trans oil level, topped off coolant, cleaned the air filter (man this 7 layer filter does great!), changed t-case oil, adjusted the spare tire to keep from rubbing on the diff, and cleaned the interior out.
all ready for my dunes trip this weekend

What style of AFE were you running before James? I run the white synthetic ones with an outerwears. Seems to let a little dust through every now and then.
