HEI conversion plug wires

I bought the jegs wires but have not put them on yet cause I'm still running points and the old hooker headers. I can't decided between 340 manifolds or dougs. I'm thinking either will have better access to plugs 5 and 7.

not sure on the manifolds or dougs but i can say tti have a ton of room for #5 and #7 plugs.. :)
