Magnum vs LA block...differences...preferences

Bumping this up. Would like to see @pishta 's feedback on the Pro Flo but.......


I just bought a MP crate Magnum block from @GTXJohn that is a NOS block. I don't have immediate plans to build it right now because I currently have engines built for all my cars but I'm just going through the brainstorming phase on it.

Some questions I have are which (LA vs. Magnum) has the better rocker gear? What is better for higher rpm and longevity, pushrod or head oiling? What head (LA or Mag)? Is one head/intake bolt configuration better (I hear valvecovers seal better on Mags)?

My plans for a future build include hyd. roller lifters, Trick Flow or Performer or Promaxx heads filled and drilled offset rockers/ pr's ..... I do also want to run an LA timing cover and w/p.

I've got the block and now just deciding on what direction to go when I see deals on parts come along. Mag heads/intake or LA heads/intake?
