I apologize for not replying sooner, been busy with other things. The transmission is currently out and the engine tilted back, so I haven't been able to pull the plugs just yet, but I'll get after it when time permits and post pictures.
I haven't done a compression test since the heads came back, but previously I saw numbers between 150-165 psi. I'm not sure if the variances were due to my cheap Chinese compression gauge or user error, or just normal variances in the cylinders. I'll run another test when I pull the plugs.
