Studs front and rear in manifolds?

Teflon tape around 3 times.

Those headers have 3 tubes hanging low, under the steering linkage. Hate them, allways get banged up.
I used the Hooker Super Comp. headers @ 1-3/4 and no tubes under the steering linkage. The only issue was the scatter sheild. Needed to dent the header for fitment. Next time, it's a sazall to the scattersheild on the E body Cuda.
