Couple questions about eq heads?

I'm wanting to do a build similar to the car craft 400hp 360 they did a few years back I have 4 good Magnum 360 motors with the stock cracked heads I plan on getting the eq heads with the LA bolt pattern beings the intakes are cheaper that way and head costs are the same... I can't seem to find anyone that still sells the mopar performance cam they used any thoughts? Also will the stock magnum flex plate work on a 904 727 converter
