John, I hope the build goes well. IF you decide to go with stock rocker arms as I've dome please keep two things in mind. I know I may have mentioned this in another post in more detail but the short version is there are two different push rod end styles and that will be predicated on the lifters you end up using and since these are non adjustable rockers you really should measure the assembled motor to determine the correct push rod length. Decking,the block, milling the heads, and using something other than a steel shim gasket can effect the correct pushrod length. I'm not sure who else has them but Carmen Fasco has the various length pushrods available.
