yeah i have working on this car for the past few dayz.its a 82 monte carlo and there was a 350 in it and they said it wouldnt run so i try'd everything and finally found out that the timming gear and chain where 6 teeth off so i fixed it and then started it and it missed very bad and then found 6 bent push-rods so i replaced all of them, now it runs but ,isses on two cylinders and i tested them and all the others have 125psi and #3 and 8 read absolutely 0psi wat the problem
please help i dont know if its a bent valve or wat so if you can help me i would apprieate it

 

bent pushrods???? probably have a few valves too maybe a hole in the pistons. Somebody did a number onthat engine. If I had found bent pushrods I would have pulled the heads. Especially if the timing gears where off that much.
