would I like to know that heads to climb on, can modify mine original? can the 5.9 heads be all right?

Thanks

The Magnum 5.2 heads and 5.9 heads are the same. They aren't horrible but its probably worth upgrading after going to 390ci. The original magnum heads also have a tendancy to crack so the ones you have may be no good. There are a few choices one being Magnum R/T heads but I saw in a magazine article about mopar magnum heads that Engine Quest heads flow well and less expensive than other choices.

he is right about the stock magnum heads cracking, you have 2 choices really, they quit making the manum rt heads but they have a new iron head, not sure who the real manufacturer is but EQ, indy, and several others have this head basically the same between all of them, the other choice is the edelbrock performer rpm heads awesome heads but they are expensive.

Who makes the stroker kit you got?
