Replace the camshaft and lifters together as a matched set rather than installing new lifters on the old cam. A small-block Chevy cam-and-lifter kit with gaskets is a practical option. The job requires removing the distributor, intake manifold, and valve covers for the lifters, plus the oil pan, timing cover, and water pump for the cam, and the lifters and timing should be set by someone experienced.
The owner of a 1988 Monte Carlo SS with a 1967 327 asked how hard noisy lifters are to change, what new ones cost, and which type to install. The expert advised against mixing new lifters with an old cam because the parts are wear-mated and will not last. They recommended a cam-and-lifter kit, cited a Summit kit around $92.40 with gaskets and shipping, and outlined the major disassembly and adjustment work involved.
