I'm am considering buying a lx (89' i think) from a friend. If i buy it, we are going to convert it to a 5.0l. I'll have to double check on the internals but, if the heads are not already after-market, I am going to get them as one of my first mods to the car. (3.73 gears already in rear-end

)
Does anyone have any suggestions for cylinder heads that won't break the bank (~$500-600) but will still perform? I will only run the car at the track once or twice a month likely. once all the right mods are added. (control arms, sub-frame connecters, ect...)
