- It has been suggested that I consider installing a copper head gasket and even a thicker gasket when I put the Judson on my 1275. As I understand it I can and should reduce the compression ratio with

- Definitely go with the copper gasket, but no need to reduce compression by using a thicker material. I've run 32 psi with copper, without any failure. If you want to get serious, O-ring the head. WF

- I am not sure about the head gasket thickness but I just replaced the head gasket on my car due to a burnt exhaust valve on #2 cylinder. The original gasket I used 10 years ago when I rebuilt the 127

- I'm putting a Judson on my 948 after break-in. All this talk about compression ratio has me worried. I had the head faced to retain the compression ratio and 10 thou shaved off the top of the block b

- Mark, first you have to determine the combustion chamber volume (v). The formula for compression ratio (CR) is CR = (V+v)/v where V = displacement of one cylinder (1275/4) Solve this equation for v t

- The process involves machining (cutting) a ring or groove around the combustion chamber on the head. Then placing a wire "O-ring" into the cut which protrudes above the surface of the head. When the

- Hi John, Long time no speak with! If you want more pressure from your pump (Judson), you need to over-drive it a bit. Change the drive pulley size. What size do you currently have? I have a 4" you mi
