performer rpm upper to lower gasket

i have an edelbrock performer rpm, uses the same gasket as the regular performer for upper to lower, but its on a brand new motor, and i keep having to take off the upper to mess with the valve train and retorque the heads...every time, the gasket from edelbrock rips and i have to get another. my stock gasket on my stock motor with what like 17 years of use and 160 thousand miles never ripped and still looked reusable. :notnice:

so is there a felpro gasket i can buy to work with this manifold? these edelbrock ones are kinda crap if you ask me, and i need to go back in there and adjust rockers, so i'd rather put a different gasket and avoid having to buy new ones all the freakin time. thanks.
