Cylinder Head CCs and Compression

I am going to purchase AL heads and I want to increase my compression ratio .
I presently have 906 heads, checked 88 cc chamber volume , and my compression is 10.1
I want to increase my Compression with the new AL heads
Question
If I order a set of heads with a 78 cc camber will this increase my CR ? if so how much?
Tips , suggestions welcome
Thanks

The 10 cc difference results in about 9/10ths of a point.

Are you sure that you want to be bumping up against 11 to 1 compression? Even with aluminum heads, that is race gas compression. I was at 10.94 to 1, aluminum heads and a big, solid Lifter Lunati 316/326 cam and it still knocked on 100 octane.

You know this because you measured everything and did the math? For a 440 to be 10/1 requires a TOTAL chamber volume of (440/8)/(10-1)=6.111 cubic inches, which converts to;
6.111 X 16.387=100cc TOTAL. Dropping 10cc I get almost same as Kern Dog.

The cylinder pressure,and loading have to married just right, to stay out of detonation. The cam is a huge player in determining pressure; seconded by elevation and SCR; and handicapped by vehicle weigh,stall,gearing, and traction.

@Kern Dog
IDK about BBs,
But,
in my closed-chamber,tight-Quench,Eddie-headed 367,
I run a tic under 11/1 with an Ica of 66*, making a tic under 180psi,on 87E10, with Power-timing of 34*@3400rpm, in a streeter;detonation-free@900ft.
Jus saying

I agree that many factors do combine to determine the outcome.
I also have changed my view on cam selection. I bought into the "Run a bigger cam to bleed off cylinder pressure" routine for awhile but have since learned different. The big cam builds MORE cylinder pressure as RPMs increase, making the detonation worse at higher rpms!
Years back when I posted my detonation troubles, there were a LOT of guys trying to help me. I was stubborn as a mule about not changing the pistons. Then, it seemed like too much work to pull the engine. It would have made all the difference with that one move. Since then, many aspects about my work, hobbies and life have changed. I no longer look for the easy way out.

That's true;
This can happen when an engines exceeds a V.E. of 1.0,
I think that would be a tough, or expensive, thing to do in a streeter . That would take a serious engine... or one with a lotta cubes; or maybe a too-small cam.I think that would be very hard to do with an alloy-headed street SBM, at legal speeds.

I sorta tried, with a Mopar 292/292/108 cam at 11.3 Scr, but failed. It ran on 87E10, and 34* of Power Timing, with a 750DP; and 3.55s/A833 .. I'm having a hard time imagining to run a bigger cam on the street.
The smallest I ran, in same 11.3 engine, was a 270/276/110 cam. That was a torque-beast. It too ran on 87E10 at 34/32 Power-Timing. But I didn't run it long like that; just a couple of months. By next spring, she was down at 10.7.. So Ima thinking, a street 367 doesn't have enough cubes. I was a lot younger 20 years ago,lol.
