I put the word out on the local muscle car forum about my 5.3 and it wasn't long before someone offered a set of headers for $100 which I will be trading design work instead of cash. They're Flowtechs that he swapped for pacesetters on his late model F-body. I know Flowtechs are probably inferior to the Pacesetters but for basically free except for 2 hours of my time I'll take 'em and put the $300 elsewhere. I'm saving the stock manifolds for a future turbo build so the headers will only be on there for a couple years anyway.
