@318willrun, The magnum heads are suppose to be a good budget cylinder head for a LA 318. My question is, with them being known for cracking would this affect the durability of the cylinder head? Does the crack get worse and cause the seats to come out or let coolant into the oil, are they worth putting money into? Same question for the 302 heads.
many magnums out there with 300,000 and run great, most likely with cracked heads. Nobody likes the idea of putting an engine together with cracked heads including me. I think spring pressure has something to do with how the cracks behave also.
