I have 1518s on a .598"/.612" cam and have taken it to the 6800 RPM rev limiter many times. EPS/LXL lobes.

Either spring will work for what your looking to do and what cam your looking to run, but I do like the added insurance that comes along with the dual spring. Either way both will take care of controlling our 233/239 camshaft without a problem. Nice choice in camshaft by the way!

IMO Pac 1518 is lighter and will control harmonics better for this cam (installed at proper height). End result will be a few more ponies as well.
