That is why a lot of guys are 'Porting' this section by making the transition deeper in the head and rounding off any corners as much a possible. Especially if you have had your heads milled, make sure you pay attention to the transition. Perfect solution, No. But it helps and together with todays oils and PCV systems, along with proper maintenance should alleviate any problems.
And yes Rick. The valve cover studs are hollow. Using the hollow stud makes it so you don't have to modify your valve covers (especially the alum T-Bird ones
).
