With the 302 heads and .024 gaskets you will be about 8.8:1.
I wouldn't spend the coin on rebuilding another set of heads, and would just run it as-is. Even with this set-up the pistons are always going to be a mile down in the hole.
Put headers, small cam, and two-plane intake on it and don't worry about the compression if you can't swap the pistons for now. Finding the heads and getting them rebuilt and swapped is way, way, more work and time and money than swapping pistons, and the 302's aren't any good for flow without a lot of port work and bigger valves anyway.
The best thing to do is re-piston and then add some good heads as time and money allows.

pistons to use would be KB167's...some other options would be to tear the motor down and get the block decked about .050 or so....
another option would be to get some enginequest 318B magnum style heads. they have about 5cc smaller chambers than the open chamber 318 heads, and with the thin head gasket should put you at 8.5-8.8:1.....you can get a set of new heads assembled with springs good for .5" lift for about $650/pr, which is a better deal than rebuilding some 302's...
