My GT Tribute with the 2L six is out of the car for some maintenance. Most of the studs on the lower valve covers have been removed and replaced with bolts. I think there are 3 or 4 still with studs/nuts. I'll be doing some vintage races and DE's with the car. Should I just go with bolts on the lowers so I can safety wire them and remove the few studs that are currently there? My engine is a 914-6 motor with the 6 hole upper and lower valve covers.
