Headers it is!! 

To be honest, I don't think 66 carbs and intake will hit that number. IMO more like $3000-range,,,plus or minus $500 I thinkWow - then just carbs and manifolds alone are hitting the $5000-6000 range.
Gotcha !!!!Bill, I was using your figure of $4k for manifolds and $1k to 2k for good carb cores (not restored) to get the $5 to $6k figure.
