I've decided to learn how to rebuild a 351w for my 69 mustang coupe, so far I'm having roller rocker arm studs put on and my flywheel turned but was wondering if there is anything else i need to do to put roller rockers on, again just learning.

 

You need to find and purchase a copy of "How to Rebuild Your Small Block Ford." Read and study it carefully. All the information you need is in there.
