240Z: Measuring & Cleaning the Block

Im a bit busy today so no big work this saturday, but still managed to find a few free minutes for the car:

1) Scraped off some old cylinder head gasket stuff with a spatula:

2) Measured the cylinder top bore, and largest i measured was 82,92mm. Actually i didn’t find any information on the standard bore on the quick (have to search for it) and on the other hand i don’t know if i even used right method and tools to measure this. probably not 😛
