Around 450, to 460, lift, 250, to 260 degrees duration, 116, centerline.

How do you change from a pressed in rocker arm stud to a threaded one?
you have to remove the pressed in studs ,and tap the hole with the proper thread size for the threaded stud. this may require drilling the heads with the proper size drill, for the tap size you need. you must make sure that the new threaded studs are bigger than the pressed in ones, or you won't be able to thread the stud holes.
What are press-studs?
The press-in studs are on the cylinder heads. That's where the rocker arms go. Press-in studs don't stay in very well in high performance applications, so most people either have there heads machined to accept screw-in studs, or buy heads that came with screw-in studs. A low-cost alternative to screw-in studs is to have the press-in studs cross drilled to accept roll pins to keep them from pulling out of the pedestals. This only applies to iron heads, as aluminum heads always come with screw-in studs.

if you can remove the broken studs without doing damage, you may be able to redrill the holes with the proper tap drill, and retap the hole for the screw in studs without removing the heads. careful you don't drill through the head, and get drill chips in the engine. i guess it depends on how good you do machine work.
