The short answer is yes, headers will get you some horsepower. Remember that the exhaust system is the entire unit from exhaust valve to tailpipe. The most benefit will occur if you can remove other restrictions, i.e., use a good free flow muffler (Flowmaster or similar). I think you can conservatively look for 20-30 horsepower with a complete free flowing system installed by a competent muffler shop. I like 2-½ pipe (others will suggest you go larger) with a cross over as shown below.

If I were you and had just completed that engine, I’d think about ceramic coated headers like Hooker 2217 or similar. They’re made for big block Camaro applications and my experience with Hooker is that they fit well. Bear in mind the ceramic coated headers are pricey ($750 from Summit!) – but they will last long after standard heavy tube steel headers no matter how well you prep and paint them.

As a side note – another obvious area (from your picture) to pick up a couple ponies and increase reliability would be to install a GM HEI distributor and use a Mallory or MSD coil.

Looks great Scottyo – let us know how you progress
