Compression
What is the compression ratio on the Model A "B" head. This is the police head. Some say 5.0 to 1, others tell me that it is 5.5 to 1. What's your thoughts. Thank you.

Re: Compression
I believe the standard 'A' is 4.2 and the 'B' or police head is 4.8.
If I'm wrong we'll know soon enough. [ smiley face] |

Re: Compression
5.2 is correct. I’m guessing 65# most important is they’re within 5# or so of each other.
