ok i'm getting ready to install the gasket and i noticed theres some stuff i really dont think i need but i want your guys opinions first before i do it. theres the orange and black end seals that i know i need to use but then theres some light blue ones that almost look the same but are a little smaller. did you guys use those? what are they? and then theres some other stuff like the thermostat housing gasket that i didnt know we needed since that rubber seal goes around it and then sits in the intake. thoughts on this? please let me know. thanks guys
