Doing a engine rebuild on my 2005 dodge 2500 and I went to cummins and priced a gasket kit upper and lower. They are pricey..... upper gasket kit is around $250. 00 and the lower kit is around $300. 00. 550. 00ish for gaskets is to high for me. I replaced the valves and they come with vavle seals, I bought a head gasket, oil pan gasket, rear main seal, so I don't need a entire kit. Does anyone have a list of what come in the upper and lower kit with part#'s? Thanks, Paul
