Thanks guys for these info. Please excuse my bad grammar. The engine has still itīs (overhauled) MFI. As iīm informed the space cam in the MFI is the same on an "E" and an "S".
This JE-pistons and cyl-set was sold over our german forum (on a acceptable price) so i decided to buy. Here are the specs:

84mm FORGED JE PISTON
BYRAL CYLINDERS,
COMPRESSION HEIGHT: 34.2mm (1.347")
PISTON TOP: 11.5mm (.453")
PISTON RINGS: TOP:1.5mm 2nd: 1.5mm OIL: 4mm

I want to keep the "E"-cams but i couldnīt find anything about the
clearance between the pistons and the valves when using the
original cams with these JE-pistons. On email requests which
i sent to JE, i got no response until now. I will unscrew my machine
and will measure it out but it would be helpful to know it if iīm in need
of some "S"-cams as they are kinda rare here in Germany.
