Ok so I was driving and my harmonic balancer fell off...the key to the bottom timing belt pully also came out some my crank was just spinning and my head wasnt so I took my head off and bam all my valves are bent.my pistons have no damage...so I was just wondering since I have ls valves laying around if they would work on my gsr head...thnx in advance

 

no they wont fit, they are way different sizes
