im almost done with my motor and i have put so much money in to the motor i dont have enough for headers at the moment. so i was wandeing if it would hurt anything if i just ran the stock manifolds to just break the motor in? keep in mind im runing cc503 p&p heads flowing 280/210 so will that phisically hurt the motor or just performance.? thanks

 

Won't "hurt" the engine.... it just won't make the power its capable of. It should be tuned accordingly.
