For headers, go with Doug's or TTI... They are the best fit and won't hang below the k-frame to be bent on daily driving...
Watch the online Autozone discounts to get the doug's at a reasonable price, it will save you about $150 - $200....
The headers may require you to run a mini starter from the later 90's trucks, order a starter for a Dakota or Ram with a 318/360 to get the proper mini starter...
