Stop in for a cup of coffee

Question for the group.
A friend, who has money, is looking at a couple MOPARS.
Both cars are done, nothing to do.
One is a 440 and one is a 426 Hemi.
He reads the Hemi's are some what of a pain have to adjust the lifters and other type maintenance.
Never had one, know little about what the require.
Comments??

I built a 426 Hemi for my dad once... It was a pain... for a 'standard' engine, I had to do alot of 'custom' work....
