Conclusive info on 4D56 head onto 4D55 block info?

Huh, I guess we just hadn't machined enough of of my old one to need that. I'll have to keep an eye on that when we rebuild it

The readily available online pdf of the 94+ service manual hives a very good description of measuring for which head gasket you need. I also found an excellent video on youtube by Ajusa(an import parts manufacturer) that shows a completed head gasket job, including measuring and head gasket selection. I do not know if it is as hyper-critical on a 4d55t(I believe cranks and stroke are biggest difference. Pistons are the same) as it is on the 56. And now, my motor is a 56 under the skin. I had to time my fuel injection pump to 4d56 specs too.
