Scattershield ID

Picked up this scattershield at Nats can't find any numbers on shield but numbers on plate come up to Lakewood small block. Couple questions for anyone that knows. Will my factory fork work(72 dart)? Also how about magnum starter? Any fitment issues with tti step headers? And just opinions what hp level or rpm would you consider it necessary? 20220816_162912.jpg 20220816_162929.jpg 20220816_162944.jpg
