This is the S2 cam and it does not want to idle at low RPM. I am also getting lousy vacuum readings (6" instead of the 13" I was told to expect) at idle. The idle is not steady (RPM drift) and the engine did not make it around the block last night without stalling and refusing to restart.
I am sure I'll get this worked out I just hate that things weren't closer to "right" when I restarted the engine.
I have one question for you guys prior to my idle/tuning troubleshooting. Most of the guides I have read all talk about re-torquing the cylinder head after a break in period. Is this really needed? I ask because of two things 1) I am lazy, and 2) I'm sure the factory never had time to do re-torque. Being a Mk1 engine, the only way for me to re-torque the head is to pull the manifolds off again. If I must... I must... but as I said, I'm lazy.
So is re-torquing really necessary? If it is... when is it done? Should the engine be at operating temperature with the cooling system free from pressure or is the re-torque done cold?
