Is it possible to bend all 8 intake valves and not the exhaust? My timing chain stretched and I think the tensioner crapped out so it may of jumped a tooth while in the car turning it with the starter. When I pulled the motor, I tried turning the motor by hand. I heard the chain slapping around and then I made contact with the valves so I put a new timing chain to make a spare motor but the noticed my intake followers were loose and not contacting the cam. After measuring the intake spring height it was a bit more than a 1/4'' lower than my exhaust spring.
