Is there a good chemical to quiet lifter in my '51 Lincoln flathead

[big job]

I smoked my brain trying to find a lifter to help you out; seems there are none on this
planet...My parts book list them for truck but no info on what year (trucks).. I hate
noisy lifters maybe take the suspect out and check it out in a bucket of oil. Reminds me
back in the day a quiet Oldmobile V8 was 1 in a million. Myself (hate to say) think I'd
put in solid lifter, those are around. I have two 1949 F8s that are quiet no clue if they
are hydraulics or solids, meanwhile I'll keep on searching

By the way I have a 13,000 mile one both ex manifolds cracked (how??) took a year
to find two good truck ones
