So, it looks like I'm going to pull the head off the Q4.

The reasons for this are, to get the old inlet manifold off and get the Lancia Kappa inlet installed, it will also allow me to address the ignition coils. I also want to get the AC pump out and I can see the hose of death at the rear of the engine starting to drip. Should also let me take a look at the started motor and decide whether that neeeds to come off as well.

The question is, if I'm going to the trouble of getting the head off, what else should I look at whilst I've got the access.

Also, what head gaskets are people using these days? Are Spesso still good, and if so the 1.6 or 1.9mm?
