question about building 2.6L

hi, i almost have all my part together to rebuild my G6 and had some questions.
what do you guys think about JIS parts? i need new valves and was thinking about going with this brand.

also, i bought a ITM gasket kit and i noticed it came with a cork oil pan gasket. is this what these motors use? i thought they used RTV sealant.

thank you

anyone?

you always want a gasket in there, rtv just helps out..iv never had a prob out of the cork style gaskets(when i put them right in the first place...lol)

thanks for the reply. do you know anything about the quality of JIS?

iv never heard of them so i dont know about them...sorry man..have you tryed looking them up on like google and see what others say
