Need High Compression 340 pistons

[SS Lancer]

I need some help locating pistons for a stock stroke 340 with a 4.080 or 40 over bore all I can find is the Heavy Sealed Power units and a few other manufacturers but they only approach 10.1 with my 65 cc Rpm cyl heads
I would like 11.1 or right around that thanks for any help .

Proceed please !!!
Looks like the only thing I can find is a 10.1 or a 12.5.1 old school heavy stuff

Adjust the ratio with head gasket thickness and/or cylinder head cc’s.

you will need custom pistons with a small dome. my 11.4:1 J E units are 513 grams.
