Why don't you get a junkyard engine with low miles. Save yourself a lot of headaches and more problems later. They go for 400-500 dollars. If you have piston damage like you say head is probably toast.

unfortunantly the closest junkyard that has a engine wants 800 for it and the nearest junkyard i could find it cheap is well over 200 miles away what am i looking at on the head bent valves and what else cuz my uncle was wanting to send it to a shop and have them machine it oh also not tht it should matter too much i had only 53000 on the car when it met my big friend the hole also i cant use anything besides a 09 or 10 engine right since i have the vvt and im already hurting a bit i didnt know the pistons were that bad so i went through my second set of bearings and a second crankshaft this one im shure can be salvaged im not shure bot the original it was in bad shape also could anyone tell me why when i had put this engine back in the rpm wouldnt work and i kept getting a bad crank sensor even after replacing the sensor

You might try searching Craigslist for an engine. I see Ecotecs pop up all the time in that $400-500 price range.
