big block rocker arms

[SanitysBane]

Hey, i got a new set of full roller rocker arms, that are 1.8:1 ration instead of the normal 1.7:1, and the stock valve covers i know that they are 2 short, but on the number 6 and 3 cylinders the intake rocker is hitting on the back side edge, i have a "new" set of valve covers off of my dads chevelle, that are tall enough but they are hitting on the side as well as the stock one. i am thinking that my only option left is to get our dremel tool out and grind the rocker down as well as the vavle cover. unless any of y'all know any thing else to do...im up for anything.

also never ever by mr. gaskets header gaskets, they are just cheap cardboard pos that will burn up no matter how tight u keep the bolts.
