Abe, there are a lot of ponies waiting for you to uncork and the gains are really noticable.I have owned 4 trucks similar to yours,I put headers on the first 3 and left the last one stock.Here is why,leaks,leaks and thin wall collectors from cheap 100 dollar headers.If you do install a set,do yuorself a favor and install a quality set and you will have no troubles.Look for 3/8 flanges,stainless steel,or at least nickel or the ultimate, pro-tec coated stainless steel.Harold knows his headers,Doug Thourly are top of the line.They provide low end response and torque at the cost of high RPM power(most trucks need torque more than RPM's)and will put a smile on your face when you hit it or are towing.They also fit great and the set I put on didnt require me to raise engine like others.Borla also makes great headers,JBA,and Arizona speed &marine.These are not cheap.I have put on Edelbroc TES headers,they are not as well built and will rust out after 3 or 4 years in salt belt,but for the money they are the best bet if you are on a tight budget.They also dont have as thick a flange and will burn out gaskets on occasion.Good luck and dont skimp-just run manifolds rather than a cheap set,you'll save a lot of aggravation.
