the heads are smog heads and I was wanting to buy a aluminum head but dont have 3g's to spend, is there a cheaper alternative?as for the car it has full interior , 9 inch moser 3.90's 35 spline axles N case center section , and its set up for a th400, not sure of weight but its probaly pretty heavy. car had a 540 in it and went 10.20's before I got it.
