i have an 04 lq4 stock internals with a set of 243 heads, well i know a guy that works for a nascar team and he ended up giving me 2 sets of nascar pistons for an ls2 they are JE pistons. i called up JE and they gave me the specs on them and ive been trying to find a set of rings for them and i have had zero luck.

the ring size is 1.2 mm 1.5 mm and a 2 mm for a 4.000 inch bore

any idea were i can get a set?

 

Have you tried total seal?
