what do you have to spend?
some trick flows or AFR's would be really nice if you can afford it

You could checkout the PRC 227 or 237 heads depending on what compression your looking to go for.

keep your heads. theyre good and will work well with the lq9. cheaper to go with what you got. that lq9 is gonna be torquey and make real good power. hit up pat g, geoff at eps or ed curtis at flowtech for a custom cam grind instead.
