At 3830 lbs to go 8.90s consistently, you will need close to a solid 1100 hp. That is a bunch. The smallest head I would even consider would be about the best ported B1Mc out there, or Predators. The weight is just killing you here. If you could shave some weight off the car and get it down 200 to 300 pounds, you can get by with the B1Mc heads most likely and not have to go with the predators, which would probably have to be bought new. A used set of B1Mcs with a good performance history is what I would look for.
