Need HELP Engine gurus inside!

OK I had a shop put my car together and I am pretty sure a valve hit a piston so here is a question...If I had a 224 563 114 comp cam, 11.1 compression 2.02 1.57 valve, LS1 head. What size pushrod would I need. And if they installed these parts with clearance issues, do you think they would be liable? Anyone know what the GM recommended preload specs are? And what would you need to mill off the head to get 11.1 compression?

Thanks
