I am doing a set for myself.
The guides were too tight and I run my guides tighter than most.
The valve job looks like it was done in 1977.
I won’t go into the rest of it because you are not going to port them (I assume you won’t be porting them) but there is no way I would not have them at least have them checked out by a competent machinist who has an actual bore gauge for valve guides.
Or not and hope your lucky horseshoe is point up so all the luck didn’t run out.
