Roller rocker install and info pls...

stock valve covers might fit if you do some grinding on the baffle but you might want to look into some aftermarket ones. also i think the fox ones might be a little taller.
 
you dont need guide plates with ped. mount rockers.

only real benefit youll see from the new rockers is that their a bit lighter and being roller rockers theyll move easier

1.7's will increase lift a tad
