Late model Big Block Chevrolet engines are originally equipped with exhaust valve rotators. Until now, the only way to make up for the rotator was to stack .300" of shims under the spring. This was sloppy but also did not fit as well as these seat spacers. These will locate the spring with an outside step so the spring cannot "walk" around on the head.
Avoid stacking .300" of shims under the valve springs on your Big Block Chevrolet with our seat spacers. These spacers feature a 1.732" outer diameter for 1.568" outer diameter springs.
The COMP Cams philosophy has never changed: make the highest performing products possible and lead the industry in technological development. One thing COMP Cams has never forgotten: Performance is defined by what happens out on the race track. Because no matter what happens on a dyno or in a computer model, if that theoretical performance doesn't translate into real-life results, then the mission isnat completed. COMP Cams spends thousands of hours working with race teams to make sure COMP Cams products provide unmatched performance and reliability. That's why every COMP Cams product offers the highest performance standards. COMP Cams competitive drive culminates at the track and in Victory Lane. COMP Cams has produced more champions than any other camshaft manufacturer.
