Description says it all.
I have a 70s small block chevy with stainless steel shorty headers. These plugs will make spark plug replacement easier.

Solves clearance problem.
These Accel spark plugs solved problems I was having regarding clearance with my headers wrapped with Titanium Heat wrap on my 350 engine in a 1979 Corvette. Before using these Accel plugs I could just barely get socket over plug to tighten as needed.These plugs solved the above problem.
