play is bad but a little bit of play may be okay, it may just need a new coupler witch is cheap and super simple to replace especilly if your blower is off the car, and yea thats way to high if your not sure if it works, a guy on here has nice heads for $200 shipped and you can find a Gen 3 for near nothing. if he wants that much dont go for it unless its for the whole set up, S/C, LIM, heads, pulleys, tensioners, crank pulley, injectors, fuel rails, bolts, etc..
