The extremely tight fitting the STS's have is mainly because they don't matche the piston and lseeve to each other, MEGA and Novarossi and all the other highend manufacturers matches the fitting in piston and sleeve so that they are perfect, with the STS engines you have to do this fitting by yourself by breaking it in
