Default 5.0 heads. who wants 25hp for free?

Im most likely going to be getting a v8 YJ here soon. it has a mustang 5.0 L in it bored .30 over, explorer intake, b303 cam, ford racing valve springs, bbk 65 mm throttle body, 70mm MAF, 24lb injectors, ceramic coated ford racing headers, and gt40p heads @ 10.5:1. (stock rotating assembly)

my question is.. I dont want to run premium fuel all the time as this will be my daily driver, and I am willing to take a slight loss on power. so what is the CC on these heads, and what heads should i put on it to drop the CR down to an 87-89 octane level? I would rather not tear the motor apart to install dish pistons

I DO NOT OWN THIS JEEP YET. THIS IS ASSUMING ALL THINGS GO TO PLAN.

but, If someone has a set of heads that would put me at the right CR, I would be willing to trade. I did some light reading, and most say these heads are good for about 25hp. please dont pummel me with offers. I need information before i make any decisions.

I grew up on small block chevy's so Im not familiar with all this ford stuff so bear with me.
