Near or above 135 would be the best number, but 130 is still really good. Just make sure all are within 5% of eachother
We did a compression test tonight and it looks like all cylinders are around 120-122. All very consistent. We were concerned because the sled has been getting pretty warm. Pistons, jugs, everything looked really good. Looks like the headgasket blew out in the middle cylinder. So thats the new project. Any recommendations when tackling this?

Still trying to figure out your even compression with the center head gasket blown.

Typically these engines are around 1:6-7 compression ratio. With 14.7psi at sea level for atmospheric....
14.7 x 6.5 = ~100psi. Now factor in some heat during compression (ideal gas law pv=rt). guessing 130-140ish psi.
Just make sure the 3 cylinders are within ~5psi of each other. My $.02.

They are very difficult to pull over without the clutch.
