Hi, i just got some new lt4 valve covers, the covers came with a rubber seal around the edge of them, is this a built in gasket or do i need to purchase something else? will i need to use RTV or some other liqued gasket to have these installed properly? also i can see that the pcv valve is in a different location, its on the side of the unit i have instead of the top, will i need a special hose for this or can i just use mine, does anyone have the part number for the hose or even the oem one (mine is really jacked up).
also, the covers didnt come with any of the bolts, does anyone know where i can get some or have the part number for em? would the dealership carry em?
lastly before i remove my current covers, i have some pro magnum RR, does anyone know if the lt4 covers will clear these?
sorry for the newb questions, just wanna do it right
thanks

 

The rockers will clear no problems.

The gaskets that are on the cover are all you need to seal them. They are not the same as standard valve cover gaskets. Use no RTV. You can use the Corvette PCV/CCV hose from TB to the RH cover.
