COMP CAMS PRO-SERIES DUAL VALVE SPRING SET,(16) FOR USE WITH HYDRAULIC ROLLER CAMS FOR SBC, BBC AND SBF CYLINDER HEADS.
These valve springs have a flat ribbon internal damper, with a dual inner spring. The internal damper is very effective in calming spring harmonics at high rpm, and offering greater overall stability to the outer spring. These springs are for use with a hydraulic roller camshaft. Not for use with flat tappet cams. Made in the USA by Comp Cams. See our other listings for a full selection of valve springs. We now use these springs in all our engines.
Most low cost valve springs are inferior to these, in our opinion. Ratings are usually inaccurate, and quality is compromised. Power loss will result from springs that have taken set, become lazy, as it may be called, much like the springs in a worn mattress. Low grade springs are notorious for loosing their vibrancy much sooner than a high quality spring. One more problem with such springs is that they are very prone to contributing to valve float at high rpm. If your springs are not quick and at the proper lb. rating, then they not only have trouble closing the valve, they also tend to cause the lifter to bounce at the peak point of the cam lobe. Springs that are rated too low are sure to cause power loss irrespective of wear. Standing height 2.10" This setup is also used on most solid flat tappet sbc cams that are above .530 lift. Not to be used with solid roller cams.
This is full set dual springs with internal dampers in each. This is a total of three components in each spring.
Some sellers refer to the internal damper as a spring and it is not. The damper does provide a slight amount of spring action but it is not classified as a spring. This auction is for a true dual spring setup.
We have used Comp and Melling valve springs for many years and have yet to experience one failure. There are several low grade springs on the market that we have encountered and we found them to be very inaccurate on lb rating, not to mention their progressive rate is erratic. This may sound like sales hype, but take our word on this. We know of many sellers offering springs that not only have lb ratings that are incorrect, but the quality is poor overall. Having the incorrect springs for your cam will most certainly cause problems.
These springs are exactly what you need for a hydraulic roller camshaft in the lift range of .440-.620 Not for use on any type of flat tappet camshaft. If you have a hyd. flat tappet camshaft, see our other listings for that spring kit. You should always use new locks and retainers with new springs. We offer many of the much needed hardware associated with valve springs. See our other listings.
You can vary slightly on recommended spring ratings for your cam and not have an issue. Give us a call if you're not sure what you need. When a cam company says what spring rating they recommend, they are telling you what is most ideal, but just remember one thing, if they do tell you that you have to have that exact spring rating, they will also tell you that they just happen to carry that spring. As said, the rating they recommend is most ideal, but does not have to be exact.
