LA, cause you have it and it has the better factory heads of the LA bunch.
You can put mag heads on.
The mag is roller..but no shaft mount, short cam snout so need adapter, new balancer for old pulleys, new intake, it's basically gonna cost you more and yield very little if any advantage other than a roller cam..which you will also have to buy new unless you like .405 lift and 0 o lap.
