LA heads on Magnum block??

Curious: Does a Magnum use the same cam bearings as an LA block?

yes i have LA heads on my magnum 408 its a 95 model block post up a pic of your deck and i can tell you if yours has the oiling provisions or not other than the oiling thing it is a direct bolt on just have to get custom length push rods i have done this exact thing and it makes great power and driveability i love my hydralic roller
