You have set up your valve train for lift within the specs but you break a rocker arm. Will the rocker arm you install in place of the broken one meet the lift spec? While setting up your valve train, check a few extra rockers to keep as spares. Be sure that the spare rocker will meet the lift spec no matter which cylinder it is placed on. In teardown we may check any cylinder and that does not necessarily mean it will be #1.

Good point I am just finishing up doing my lift measurements and sure enough 1 or 2 rocker arms were .002 - .004 over the max lift. Had to do a little juggling to get everything in spec. Actually didnt think about measuring some spares, break one in eliminations you barely have enough time to change said rocker let alone measure it (been there done that)!
