5.9 stroker build

I've been skimming through the "Rebuilding the Mopar small block" books that are available along with watching some YouTube videos on the subject.
Last night I saw one of those shows from the mid 2000s with a couple of guys that never got dirty, they were probably just actors that spoke in proper cadence, stood the way they were supposed to and smiles a lot. Those shows sometimes have the guys talk about the next thing they are going to do , then go to a commercial then return with the task completed....skipping right over some key points.
One was where they took a Magnum series block and put Edelbrock heads on it. I've read that when you switch from the rocker arm/hollow pushrod oiling that the Magnums had to a traditional LA series head, something has to be done to get oil to the rocker shafts. That one video skipped right past that which is a terrible disservice to any newbie that wanted to take their advice on a similar build.
I only learned a couple months ago that the Magnum blocks had a slightly shorter deck height.
I just read recently how small the combustion chambers are in the Magnum heads too. 60 ccs ? That is crazy!
The OP has the great fortune of a rich environment HERE, there are several well informed and helpful members that are sure to chime in with advice with this project.
