987-16 - Comp Cams Dual Valve Springs is rated 5.0 out of 5 by 1.

Rated 5 out of 5 by Derrickmac2 from Very nice I bought these since i run a 347 stroker in a 89 mustang gt with edelbrock performer heads, the spring pressures were dead on as advertised. Only complaint i had was im holding a 1.800 install height, these springs are advertised as 1.750 install on jegs website, however when they showed up the sticker said 1.800 and measured out at 1.800 so ended up wasting money on +.050 retainer locks. I havnt got to fire the car up yet but everything looked great we shall see
