C/R estimate

C/R estimate
so, i had some JE pistons installed a while back which gave me compression test results of 135psi. this is on a stock IX engine.
i've since pulled them out and replaced with OEM which now reads 145psi (264 cams, which is why i'm assuming a bit lower than stock).
nothing else has changed so, based on the C/R of an OEM IX engine, can anyone make an educated guess on the C/R of the JEs?
or is it impossible without knowing all measurements and specs. i want to sell the pistons, but i'm sure the buyer would like to have an idea of what they are getting LOL.

They look identical to stock, but I can post a pic anyway.

i won't be using these. i took them out because i was disappointed in the power i was making. low comp is great when going for big power, but i have an HTA71 so can't really take advantage of a lower compression piston.
these are better suited for someone looking to run more than 25psi.
