It could be an exhaust leak, that might be a good place to start. Did you do headers at any point? It sounds like there could be more than one thing wrong with it but that could be the source of th ticking sound.

Could be a piston skirt,valve hitting piston(broken spring) I wouldn't run it any more until the problem is found. Ya may sacrifice your block and a head if ya do. MORE$$$$$$$
