500t head volume vs 450? anyone ever measure it?

some say the 500t head has more volume in the dome, i.e. less compression. I can see it is a different casting, and has not got the steel dome in it. does it also have a slightly bigger volume, that is to say it is lower compression?
I observe that the pistons have less dome than the 450; what about the head?

thanks, Brian

...Paul (Dinosaurthatroars) at the MSN site reported that simply replacing the 500T head with a 450 one would increase the compression ratio...Assuming that is true, and all the other 500T parts remained the same, the 450 head would have a slightly smaller "space" or volume within the dome.....
