well, about the smoke coming out of both sides of the exhaust, the 300zx stock exhaust does meet at one spot and the splits again, so it could only be one head blown, but if you were going to change one, it would probably be safe to change both at the same time, considering how much stuff has to be removed for the job, and you probably don't want to do the job twice, also make sure you get the heads resurfaced, otherwise you would have wasted your time and money, but about price, it will be a hefty one unless you do it yourself, you may even consider a engine swap.
