Need some advise on these issues

I'm rebuilding and spicing up a Chevy 292. I got all parts and advise from Clifford. I have learned after, that they advise totally different than the gurus.

What I was told to do:
mill head to 63cc chambers
O-deck the block
1.94/1.50 valves.
.030 bored

The rest of the setup is:
2 x 32/36 Webers
264 Clifford cam
Alloy pistons with a 16cc chamber

All the machine work is done.
I just measured the chambers in the head to be 66cc and the pistons to have a chamber on 16 cc.

Is this in your eyes a too high compression?

Another problem is that the #1 piston top is .011 over block (it does not flush the deck) the #6 piston does flush the deck perfectly.
#2-5 all is a little over the deck hight.

Should I mill the pistons so they all flush the deck to get an even compression or does it not matter?

I'm NOT going to race the engine, but use it in my 1950 Chevy PU. I'm going to use it 3-5000 miles a year (summer)

Hope you have time and want to comment my little issues.. sick

Thanks.
