The iron vs aluminum cylinder head argument is over.

After reading all the posts here, albeit often Edelbrock, not just China production quality, I didn’t trust the springs, valve guides, people mentioned helicoils (MRL?) and after those comments, and learning here how important sealing the valve was, I just opted for a red blooded old timer machinist to assemble one of my sets.

I just lost my assets to Dvorak Machine, so I have to collect all the small parts again to populate the engine.

If you don’t get them checked out, I honestly hope you turn out alright. But I would be nervous for you.
I'll check them out myself but I'm not nervous one bit. The only thing that would even remotely make me nervous is the internet. The set thing I got sent to my door look like perfect jewels! It's just this internet that puts the Boogeyman in people's heads..
You got to have them checked out you got to do this you got to do that when you break it in you got to remove the inner Springs blah blah blah..
I'm 100% fine with everything and the word China doesn't scare me.. if the word China scared me then I shouldn't have drank that apple juice at the hospital..
