Briggs 5hp compression

[Jjtwospeed]

Can anyone tell me how much compression a 5hp briggs flat head (1967) should have to be considered good compression.Just purchased a model 130212 that has low hours that runs good and I hope I won’t need to split the case.
Thank You

70 to 80 or higher should be good........
