1991 Chevy Camaro clutch Master cylinder

Transmission problem
1991 Chevy Camaro V8 Two Wheel Drive Manual

i own a 91 camaro rs, originally a lo3 5.0 TBI 5-speed. I did an engine swamp so is now a 5.7 2 bolt main 350 from a 73 truck. Im down to getting the car moving but I cut the clutch master cylinder hard line when I was doing the swamp. I replaced it, but when I tried to press the pedal the slave cylinder began to leak. I replaced it with a new cylinder but this time the push rod on the clutch master cylinder bent. I have warranty on it so I went an got it replaced, and re installed it. I had a friend come over who has done mechanic work in the past to bleed it for me. We filled the resivor an began with the process when again the push rod bent and snapped in the same point or close to the last one. The push rod lined up and pivoted fine on the pedal assembly and was flat against the fire wall so im not sure what the problem is. Any ideas? I have a new slave cylinder and a performance clutch in it, so I dont know if that makes any difference.
