Banks is great gear, but really expensive and they don't make a system for an 83.
Maybe the system from an 87 would work? Although the ones I have seen are 8-2-1 and my RV has a dual 4-1 system with an H crossover pipe.
I poked around j-d. I was able to find a set of Hedman long tubes for $215. I should have them by Tuesday. Now the big challenge will be removing the old manifolds with the rusted on bolts. I already replaced the passenger side bolts and ended up with one sheared flush to the block. I used a gasket and high temp. RTV to seal it, but I know it's just gonna blow out eventually.
Since the shop would charge me $600+ (barring a sheared bolt) to pull the manifolds and since I can use headers, I am just going to grind off the remaining bolt heads from the driver's side (I already took out three)and cut up the manifold if need be. That will leave me with the bolt bodies sticking out of the block. Then I will be able to get some heat and PB blaster directly to the threads and (hopefully) get the remaining bolts removed cleanly.
I will take another look at that bolt stuck in the passenger side. I might take it in and have the shop try to get it out. If they say the head has to come off, then I might just have them pull both heads and go for the exhaust side porting.
