Cam Tower Shim Kit, L-Series Engines 70-83 Z/ZX

Cam Tower Shim Kit, L-Series Engines 70-83 Z/ZXQuantity in Basket:none
Code: 10-1151

Most valve jobs or engine rebuilds will require some level of machining of the head surface. L-Series heads are designed for specific valve train sizing and geometry, so when the head is milled beyond a certain amount (7 thousandths), these cam tower shims must be installed to put the geometry back into alignment. Each kit includes 5 shims (one shim per cam tower), which will re-align the camshaft on one head by 15 thousandths. In the event that further adjustment is required, a second set of shims will be needed. (Note: The most an L-Series cylinder head should be shimmed is 45 thousandths.) Professional installation recommended.
