Hi everybody!
It took time tome to continue in the lincoln y-block.
I've ordered a ridge reamer to take away the ridge, which enables me to take out the pistons.
Thanks to previous tips. I've ordered a set of thelescopic gauges and a large micrometer to measure the bores for ovality and taper.
The specs are in the pdf file I've attached to earlier posts.
I've never used a ridge reamer before and hope somebody can advice on the do's and don'ts.
Today I started with disassembly of the rockerarm assembly. All rockers and caps were frozen. No movement at all.

Took some time, wd40 and hammering with a rubber hammer to get the parts loosened from the shaft.
The picture is somehow distorted, but the shaft is straight.


All oilholes in rocker were blocked as well

Here is a result of lack of lubrication.
Does anyone know if I can reuse the shaft? I will post some dimensions next time of nominal diameter and worn diameter.

Well they told me to install the carter pan and put in the oil and the engine would run fine. The first result would be bent pushrods or bent valves.....
Well that's it for now.
I'm looking foreward to your replies and to my reamer (birthday present)
