454 compression test

Alright guys, I'm continuing my build on my 454. I put new umbrella valve seals in yesterday. Today I put the heads back on the block using felpro 1047 head gaskets and arp . The engine looks stock 781 heads flat pistons w/ the little dich in the center. Tomm im doing a compression test. What compression numbers should I look for?
