Like the title says the exhaust cam jumped 180 on first start. We set the back to o-o and it fires fine but sounds like a valve is bent in cy 3 or 4 (loud ticks in low rpm but goes away in high rmp. Did a compression check-180 across the board -_-. We're screwed huh? Gona pull the head in a few days, but he's talking about parting it. Any help is appreciated.

B18c bottom (build by a friend, we dident check clearances or plastigauge 0_o)
Pr3 head (valve job done)
Ctr cams
Bloxs cam gears and dual valve springs
