Also depends on what type of studs you are using. Do your screw in studs have a nut on them to tighten them with? If so, you are going to have to have the stud bosses machined down to make them all flat and allow for the extra space the nut takes up, usually aroun .100" or something like that??? Maybe someone with a good memory will jump in here and remember that dimension....

well it dose not if you want steel guids then yes you need to cut them down if it is a stock head and you want steel guid plates if not stock then you need studs with a shoulder to hold the guid plates down and some guys go to a 7/16 BBC for a better stud and you can get the rockers for the bigger studs i have cut the sbc chevys and olds and Ford and drill them for it is about 125up from the spot face of the head bolt or so for the sbc for plates

Thanks for clarifying, Pat. Been about 20 years since I've done any automotive machine operations. Sometimes my memory of it is a bit fuzzy!!! Heck, I think it's a good day now if I remember my name!!!! Good thing the shop is now only 20 steps out the back door or I'd probably get lost on the way to work!!!!
