don't waste time milling heads. if your going to do, go about .06 off the bottom and have them fix the intake side as well. you'll find that will cost about $300 for the pair. at that point i'd buy the sidewinder heads or something else. for the slight bump in compression you'll never feel it. not worth the money
Doesnt sound like it would be worth the money then. That would almost double how much im into the whole motor
