IE cast Pistons 9.5:1 E21 head

I'd be shocked if 9.5:1 pistons for an E21 head also fit a 121ti head!  And why does the third photo in the original post refer to an E12 head?  The E21 and E12 heads are similar but at a 9.5:1 compression ratio, I believe their pistons are also not interchangeable (without modifications).

 

Regards,

 

Steve

9.5:1 pistons for a E21 head WILL NOT clear any other cylinder head (118,121, 121ti, E12) without either modifying the head or piston for clearance.  Those are Cast pistons.
