desperatly need engine help

No the guy told me he was just telling me what he was told about the this engine before he bought it. I bought this supposed rebuilt engine to save some time because i had a deadline to reach at the time. i took the other engine out and dismantled it, then ended up buying this engine with roller assembly already done, and used my engine parts for it. My friend came and did the cam and timing assembly, and i just put everything on the engine, like heads, intake, timing cover waterpump, pan and all accesories and put it back in the car. so no i didnt assemble the rolling assembly and stuff cuz it was all together. gonna do a little exploring still and if it dosent look good im taking it back. im starting to work 6/10's this month so i may just have to park it for awhile :(
