rough idle/ hissing noise

[brank1992]

back once again, its been running pretty good since ive been tuning and i put 750cc injectors in, but as i was doing the injectors the cam sensor started messing up because the connections were getting loose from working next to it, i fixed them up and it would run fine till they got loose again, but then i accidently hooked the red and black backwards , switched them back to normal but had a rough idle and hissing noise somewhere, didnt get to TB in time to hold the throttle so i didnt hear where it came from. the cam sensor was fried so i replaced it and got a new connector for it cause it was junk. went to start it, timing jumped up to about 60 degrees, tried again and it ran but still rough idle under 1000 and wants to stall. i can give it gas and it will sound smooth above 1000, still have hissing noise. checked for vaccum leaks found nothing. also checked timing, it lined up fine. then i had my brother start it for me so i could find out where the hissing noise came from but i heard clunk clunk clunk as it was cranking. stopped trying to start it at that point. here is a log

probably bent valve :/ getting a cylinder leak down tester today, have a cylinder head waiting for me just incase. any other input would be appreciated
