Eddie Head Question

Anyone using these heads? 318/340/360 or Magnum? Issues? What Rockers are you using? Performance? Are there accessory holes in heads (drilled and tapped)?

I currently have an LA motor with the factory stock magnum heads. Was going to go with the 318/340/360 heads but relation of mine advised me to go with the magnum to get away from the shaft mtd rockers.

Thanks,
Eric
