well if they come with black onxy gaskets then i wont get it from them. i liked the idea of getting the whole kit because of everything else it came with. my trucks going to marty this week so i need to get parts ASAP!!! i need that whole kit, studs, new stand pipes and plugs and stc fitting. my total was around $980 so if these guys dont work out, if someone could point me in the right direction i'd appreciate it. but i dont know if anyone else will sell that whole upper engine kit like these guys do, but im sure im wrong.
