I took 2 of em apart just to verify. I checked all the cam lobes with my dial indicator and they are all checking good, turned the motor over 2 revolutions. Shined a light through the lifter bores and all the lobes look like they broke in great. I just took it as a bad batch of lifters. I'm ordering a new cam this morning. I've thought, well, what would dad have done and it came to me, heck, he would have pulled the whole motor down "just to be on the safe side" as he would say, lol. I really need the space in my garage pretty quick but I also really really need the little money in my wallet not to mention wasting my parts.
There's a reason your Father had the opinions he did on these things- and you are wise to follow his lead on such matters. I cannot help but think you've chosen the best and safest path. When the cost associated w/changing the cam and lifters now
is compared to the possible costs involved w/chancing it, the choice becomes even more clear IMHO.
