Yeah, every one has cracked exhaust seats, but work fine.

Still, the all-new Australian EQ heads flow like Edelbrocks for 1/2 the price.

The overall Magnum engine "package" has lots of other upgrades, serp. belt / tensioner, much better water pump, etc.

Keeping the OEM (junkyard) SMPI is also easy, and an AWESOME swap.

If you've gotta stay with LA heads (really bucks down), #308 castings (90-92 360) are the winners. "X" intake ports, near-W-2 exhausts.
