AFR MOPAR 340 HEAD TEST!

i agree whole heartedly. if you're starting from zero or your stuff needs work *something* aftermarket makes the most sense economy wise.

question: are the AFR's good enough to run OOTB? or do they need a once thru? and if they do what's the coin for that?
I bought the set on the rodney dangerfield 318 bare from my supplier, and used there "house brand" (liberty performance) LS valves and spring package. They needed nothing, clearance was good, and valve job was nice also. So that set at least, were just bolt together and run.
