No, I don't have a 305 motor built. I need to get new headers for the car anyway, I was just curious what some racers use on their 305's. I guess I was just wondering if 1 3/4" primaries would hurt the 305 a lot. Maybe 1 5/8" stepped to 1 3/4" would be a better option. I know headers should be bought for the specific engine combo they are bolted to, but I just wanted to have a set that could work OK on another motor as well (such as Vortec 350/330). Maybe a Vortec 350 only needs 1 5/8" anyway? Sorry for rambling, but this is a good place to learn stuff. Thanks.
