Ah yes the old hydraulic lifter not pumping-up right away makes sense, we have three intake valves and the OP's seems to be a very substantial intake volume loss unless 2 or 3 are acting up not just 1, back in the day when I was a pup working a Vette resto shop the tech used to soak the lifters in oil before put a head back together and I remember asking him why, even though most of the rebuilds had solid lifters on the HP 327, 396 and 427's and really none on the 350 or 454's....the good old days
