'89 360 LA valve spring/cam confusion

what was the donor vin was it a tbi?
what now carb, headers or ?
Im looking at the Elgin catalog
do you have or had rotarors?
several cams available
or just change the timing chain and stay stock and be happy
with that rear gear and stock compression you do not want to go big
Elgin Industries

ps if it says 2011 lifters that may not a HR cam or may be a typo check
