Follow Edelbrocks instructions or don't your going to get answers on both sides of the question If you think the people who say pump em up are right and all the people who say don't plus Edelbrock, VooDoo, Crane, Howards, ETC, who engeneered and designed the product are wrong!! Do as you wish!
Its your engine
Do your tech sheets read different then this? Do they say pump them up?
1. Coat cam lobes and bottom of each lifter with MOS2 lube supplied
with your kit. This will prevent cam lobe and lifter
wear from occurring during initial engine start up. Do NOT
pre-oil or "pump-up" lifters before installation as this may
hold valves off the valve seat leading to loss of compression
and/or bent valves during initial engine start up.
