55 chevy truck build and intro

[lotussutol]

Here are some more pics. I have the headers mocked up. On the passenger side I have a little less then half an inch clearance. will be a little less with a gasket. How much clearance do I need?

I am not sure what the headers were made for...i heard for a truck but who knows what year.

I was told they are Doug something or another headers. The flanges are nice and thick. I need to clean them up before bolting them on.

I am going to run some straight 2.5" pipe into cherry bomb glasspacks dumping right in front of the rear tires. It should be fairly loud.
