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.
