For sure after all the quality control issues I've read about with those I'm gonna buy the heads bare, port them a bit myself, then have a shop do the valve job and check the guides. Honestly the only reason I put on Magnums in the first place was because of the closed chambers, unfortunately they are the only factory heads for 360s configured that way. LA-style heads with shaft rockers, LA manifold mounting AND closed chambers would be optimal for me. Needs to lose some weight off the front end as well my car has like a 56/44 weight distribution lol; definitely gonna relocate battery to the trunk, also thinking of ditching the power steering.
