i am new to the car game so i don't know much about it,but a friend has a set of 351w heads for my 93,before i buy them is there somthing i should look for or is it worth it? are they better than stock 302 heads? also i want to replace the aod with a c-4. any opinions apreciated.
Whether they are better or not or worth getting depends what year the castings are. The casting number is on the underside of the intake ports facing the lifters. It's just about impossible to see with the heads installed.
