who runs 13sec to 12.80 in the 1/4

As I said before, you either go to small claims or just take the hit and go on. As so many others have all ready said, you are going to need new pistons if you want to run the #s you mentioned. That is, unless you plan on running a supercharger & we know that is not going to happen so please no multi-threads about superchargers) .

I know money is an issue but if I were you, I would hit up the parental units or save up until you have the money to build it using old and new parts that are not going to work well together. Be patient and save up.
