Does the jessel system fit under stock valve covers and without any mods?

jesel is not needed unless you're running a pretty big cam, they are the best but also a lot more $, with the 7/16th stud just buy a set of good quality full roller rockers, a lot of heat is generated at the pivot point a full roller lifter has needle bearings in the pivot location, you can grind the edge of the corner lifters to clear your valve covers or just buy a set of inexspensive valve covers.

OK, thanks to all for the input so far.
I am convinced to go with full roller rockers.
What stainless steel roller rockers would be good and fit under the stock cover? It seems some members have had issues with the aluminum ones, although that may be on higher lift applications. (I am running a .527/.544 lift roller cam)

Any advice would be greatly appreciated.
