Good luck. Almost all headers suck in comparison to factory manifolds in regards to plug clearance

I have on my 80 Camaro with Speed Engineering 1.75" long tube China made headers. I use stock GM wires but I always use the stock tin shields that goes on each spark plug but to prevent header tube the from touching the boot.

I’ve always used MSD wires where you can bend the boot to help keep the wires away from the primaries. For good measure I’ve always used the fabric heat resistant boot covers. Never melted a wire.
