I still assume it's 2.11'' for the intake and 1.77 for the exhaust.

I will take the heads to a machine shop to fix the surface, valve seats and pressure test them to make sure they are good.

All 8 cylinders has low compression yes.
He mounted new pistons, honed the block, new cam, new lifters and new rockerarms.. Then he apparently ran it for 20 minutes and then it died 😅.
It should be noted he doesn't really know much about engines and is quite inexperienced (as me..)

Thanks again everyone!

Check the cam phasing and also check if the cam went flat.
