Complete set of Crane true roller 1.6 ratio rocker arms for small block Chev. They have about 5,000 miles on them. They came from my stroker engine, before I hopped it up this summer. They will require the use of guide plates for the pushrods and are meant for 3/8" rocker studs. One is missing a C-clip (see photos), but should be available locally for a few dollars or less.
