If I purchased another set, I would still have them checked. Mine are from the second batch sold (had to wait as initial batch sold out quickly) and I had them checked at the machine shop along with all my engine parts. They found 5 valves with hair thin valve to seat contact area. I would not have believed them had I not seen it myself before I ok'd the 3 angle valve job. I would say that they were coming with marginal single angle valve jobs when I purchased mine early on. I'm glad I had them checked. Now if you add what I paid to have them redone and the cost of them then it puts you real close to a set of Eddy's made in USA......
not a sermon, just a thought.
EDDY's are ANGLED spark plugs, 440 Stealth are STRAIGHT spark plugs. That alone is enough of a difference to me to choose the 440 Stealth heads. This is something that no one seems to mention. It can make a HUGE difference in wire clearance with headers or exhaust manifolds. Always check EVERYTHING before you bolt it on. Then take it off, adjust as needed, and CHECK again. Only a fool just bolts it on and hopes and prays.

The thing is though, edelbrocks and mopar heads don not look stock at all, so if that is a concearn for you, the 440 source head is the ONLY alternative for an aluminum head that looks like a 906,452.........

I do agree that I hear many say the angled plugs give them problems but on my 63 with the EZ heads I use they have the angled plugs also like the Eddy's. But for me it actually gave me more clearance for my plug wires at the headers tubes. They angle the right way to help with the TTI 2" headers. And my son has the RPM heads on the 400 in his Dart with the older CPPA headers and it has more room also with the angled plugs. From what I understand it matters as to what headers you are using.

I found that Heddman Elite headers fit the Edelbrocks, there's not
many out there that look like they'll work with the angle plugs.
If you don't have headers yet, no big deal.
