The iron vs aluminum cylinder head argument is over.

I didn’t do any research at all on their valves or springs because I’m just using Edelbrock stuff I already had sitting on my shelf that I may have never used. Doing that shop cleanup last month and labeling everything pays off making a deal a super deal.
I just hear a lot of people wanting to put quote "good" hardware in their heads and I'm not understanding what's wrong with the stuff that's in there..
