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

In comment to steel heads making more power. I don't wish to argue the point because it is true to an extent. Aluminum heads dissipate heat better, and generally allow you to run more compression, more compression, more power, and yes they weigh substantially less than their steel counterparts. However all things equal on a relatively stock engine with equal compression ratios, the steel heads would probably make more power. Just my .02 opinion.
