Use Loctite on head geasket install?
Found this interesting article. I have not been using loctite anywhere on the head gasket. Maybe that's why it was misfiring when it was put back together? Thoughts

"Cylinder Head Caution for Mercedes M112 and M113 Engines
Sealing surfaces of the crankcase and cylinder heads are provided with an 0.8 mm thick silicone layer (Loctite 5900) during standard factory assembly. Silicone sealant should be applied during repair assembly only if sink holes exist in the sealing area.
When cleaning sealing surfaces of the factory applied silicone sealant, during cylinder head reassembly, extreme care must be taken in order not to scratch or damage the sealing surfaces.
DO NOT use any gasket removal materials that are abrasive. Failure to follow this procedure could result in severe and permanent engine damage. "
