aluminum vs. cast iron heads

I did not find any of these problems with the Eldelbrock heads. I took them to my machinist & had him inspect them & check for valve seal. All were ok. I'm very impressed with the out of the box performance. The only thing I changed was the valve springs to match my camshaft. As for the port finish, if you look down the carb opening to where the intake meets the head, you could not have ported these any closer. They match that well. I run a mild 360 combo (11.47 @ 116mph ) in a 3360 lbs street car. These are unported, out of the box heads. Just think what they will do when they are ported. Also, they can be repaired if you have an engine failure. It was the best $1200.00 I ever spent.

Im not arguing but based on my experience I would ask if he pulled all the valves and checked all the short turns,as well as measured the bowls.They will run but the quality is not as good as a set of heads done at a quality machine shop.Most of the sets I have seen you could see daylight at the valve,the only thing sealing it was the spring,and this was two different shops and with amc,mopar,and chevy edelbrock rpm heads.Also the flow numbers out of the box on the la heads were in the 230s,he did a comparrison to a set of ported iron I did that flowed 255 @.500 in back to back tests so no matter how its sliced they flowed considerably less than the ported 596s.
