No, You're right to be cautious, install the cam w/lube on the journals only. Don't drop the lifters in until you've got the heads on and are ready to put the pushrods in, that's
when you apply the break-in lube, roll the engine around once to make sure you've got 'em covered. The shorter the time between then & start-up the better. I prime the oil
system, make sure the carb is full & not leaking by priming w/a "puckity-puck" electric pump, & I pre-time the dizzy to a base value around 8-10deg.BTDC.
