Mark IV big block convert to roller cam

Does anyone know what all is needed to switch to a hyd. roller cam in a 1976 (I believe Mark IV) 454?

Roller cam
Roller lifters
Correct gear for distrib. (mine is shot)
Thrust button
Correct length pushrods

Is this an accurate list? Is this all I need?

Thanks

Yup, that's about it.

Big blocks are even worse about valve springs than small blocks though; make sure they're up to the task. Stock ones are TFT. Looking at your cam specs, you obviously don't have those at least.
