1933 stock v8 40 compression test results & advice welcome

[torpedo]

Dear fordbarn members,
I regularly read posts on this forum and I learn a lot thanks to your contributions.
My car is a stock v8 model 40 that was manufactured 1Q 1933. It has a Stromberg 97, stock helmet distributor and still on 6V pos ground.
The engine was fully restored presumably in 1995 and never suffered failures.
I am in the course of replacing the distributor (supplied by Mike @ Thirdgen ).
Needed to sanity check the engine so took compression and results as follows
Cyl 1-> 77 psi
Cyl 2-> 72 psi
Cyl 3-> 74 psi
Cyl 4-> 75 psi
Cyl 5-> 72 psi
Cyl 6-> 72 psi
Cyl 7-> 80 psi
Cyl 8-> 80 psi

Q1: should i be worried about the above numbers ? Any useful comment ?
Q2: Any hint/advice on best way to remove helmet dist. without removing radiator ? A guy on this forum stated it can be done from bottom up after gen-fan assembly is removed and another guy explained it is best removed from underneath. What is the best way to do it ?

Your advice will be very much welcome.
Max
