Is that all you got? You can't be seriously telling me you rather trust these numbers you find on internet sales sites than the knowledge, info and saws we have on shelf!

You can't use a non ported piston in a cylinder meant to use ported pistons. Transference won't work! Nothing can come up from case.
You cant put a 44 piston in a 444, you can't put a 55 in a 254 or 2054/2055.

If it is finger ported you might get away with lost performance but closed port cylinders will not run unless piston is ported!

This guy is selling a 55 piston as 2054 piston. The poor bastard buying it will need a ported piston.

They have same number but in two seperate brands. It is not same piston used in them!
