1996 Buick Riviera #6 cylinder low compression

My car was fine and then I started to hear a little ticking but it only got worse so I shut it off quickly I took it to my shop and took the plugs out #6 was bent over to no gap not smashed I did a compression test # 6 had 30 psi #4 had 110psi the ticking only occured like when you rev it up and it starts comming back down to idle the car still runs pretty good it just acts like it has a SMALL miss but 30psi scars me alittle and the tick getting worse 3800 supercharged series ll
