The heads were done when I got them and touched up by a friend.  the opening of the intake port is about a 1.2 x 2.10, and pretty even throughout, so they are abot a 180-185cc comparable.
It has DSS flat top Pistons and A 60cc chamber on the head but they were shaved 20thou.

What is your deck height? (or how far are the pistons in the hole?

The pistons are just about flush with the deck, maybe about +.005

You are probably closer to 9:1. I am at 9.5:1, but my heads are milled to 54cc(Speed Pro flat tops, .004-.006" in the hole)

Well I never made it to the track.  I had the car out and I am having problems.  The  car makes the power but stops climbing in the rpm at like 6000.  I figure I should be able to shift at at least like 6300 or so.  I lost some spring pressure so im gonna throw a new set of sprins in it and see if that makes the motor happy!

I checked the part number on the pistons I have. They are rated at 9.75:1 with a 60 cc chamber.  I had the head resurfaced with .020 taken off.  the original gasket thickness was .040, so I went to a .051, but tightened up the bore from a 4.100 to a 4.060.  so taking this into consideration, you still think im losing that much?

I will say that getting a TRUE 10:1 flat top 302 is more involved than most think. Next time you have a head off, take some time to "cc" everything. You will be suprised at what you find.

Yeah, I know that people lose TONS more than they think with the head gasket and all the piston height.  I Figured I would be closer on the mark with the tighter head gasket and milled head.  For now im more concerned with some other problems.Hopefully the next tim eI get TOO involved with this motor,(like it ever stops anyway) it will be to take it out and put a 408 in.
