'89 360 LA valve spring/cam confusion

I'll get some this morning. The 89-91 369 truck motor was a LA block with hydraulic roller cam, oil through pushrods & magnum rockers & .660 pushrod holes in the heads but had the intake manifold holes for the LA style. They were also the "308" casting heads. Not sure why Dodge did that, guess they got bored! I got the correct info from Rob at Rob's Rod Shop in Downington, PA as he has a considerable amount of experience with the Magnum head, LA block motors.
