I am sure yes. They are old stock I bought the car in 93 they came with it. I had those pistons and a crane ssh 320 nc cam. I still have everything the cam is rusted and has pits though its a shame it seemed like an aggressive setup when I had it together. i wish I could still run that cam. i suppose i could but I fear the cam would start coming apart in small metal shavings as it has pits in the lobe surfaces.
