Tweet

your not going to find any with baffles that clear the stud girdles .the steel roller rockers arms fit under stock short GM covers with thick gaskets made by Mr gasket . they make a mid size covers that look like stock tin Gm covers there are many tall covers that will clear your set up so use the shorter covers with out girdles if iron heads ? there no need to use a girdles on hyd roller cams or iron head small lift cams under 700. soild roller cam engines or go with tall covers . check your stud girdles could be moved down on the rocker girdle nuts .. check this ..at rest make sure the rocker bodys clear under side of girdles . so you can push in the beathers with a short grommets .if you find some room you could use a moroso baffle #68790 but may of the rocker stud girdles work like a baffle. or make one .CV Products makes weld in baffle tubes stand offs that a open filter breather fit over or moroso #68800 many times tall covers the holes are not in the covers so you can move the beather to the back and up corner of cover that way girdles are not in the way
