70 Riviera (Stage-1 455?)

[Hawaii69]

I have a 70 Riv I am parting out. I was told the 455 is a stage 1. How could I verify that this is true without removing the heads to see the valves on the bottom side.:Do No:
I wonder if there are numbers somewhere on the block, heads, dist, etc...:bglasses:
Would someone let me know. The car's down in my parking garage and I would like to check it out to verify the stage-1 mystery.:beer
Thanks & Aloha,
Scott

You can't verify without pulling the heads. Reg. and Stage 1 heads have the same casting #'s and the only way to be sure is to pull the heads and see.
