SBC BBC CHEVY SBF INNER VALVE SPRINGS FOR ROLLER CAMSHAFT UPGRADE.

These valve springs are for upgrading to a hydraulic roller cam from a hydraulic flat tappet when using our outer springs. Many people have purchased our cylinder heads with a flat tappet hardware setup and later choose to upgrade to a roller cam. This is exactly what you will need to add to your existing springs, and as mentioned they work perfectly with our # 272 outer springs, and may work with others on the market. If you are doing a hyd. roller cam upgrade you will also need to change out your valves to the .200 long size. These inner springs when used with our outer springs will accomodate a wide range of hyd. roller cams from 610 lift on down. Many of our customers have upgraded to roller cams in the past, and call us to find out what all they will need to change out, and these springs are exactly what you will need. We have an abundance of them, due to the fact we ordered more than needed. We are offering these springs at a greatly reduced price, and when they are gone, the price will increase considerably.To achieve perfect spring height you may need to shim the springs, or possibly remove some of the existing shims that are in your currant setup. Always use a spring height checking device. See our other listings for many much needed valve train accessories.

This is full set inner springs.

The chart at the right side of the page is what your complete springs will be rated at when you have added these inner springs to your existing # 272 springs. This chart is only relative if you couple the inner springs with our existing springs that you have in your heads providing you purchased the heads from us or from someone that uses springs like ours.

If you have purchased a set of our heads setup for a hyd. flat tappet cam, (sbc, bbc, ford or bbc) in the past 5 years, then those springs are all # 272 series springs used in them. You may get by with out having to upgrade to the longer valves when going to a roller cam if you use a +50 set of valve locks, but the spring pressure is a bit on the high side. We actually do set some of our heads up with this increased pressure for racing applications, but for street use your best suited to go with the .200 longer valves.
