I’m working on a 64 sbc 283 in a 64 Malibu . The engine was recently rebuilt to stock buy a local garage less than 1000 miles ago and just broke a rocker stud off . I’ve replaced the stud but noticed all the rockers are really tight, no play at all in any position. Shouldn’t there be at least a little play in them ? I can’t find a spec for gapping for between the rocker and valve springs any help would be appreciated. Sent from my iPhone using H.A.M.B.
