Re: 440 source heads

[Dave Casey <dcasey@xxxxxxxxxxxxx>]

I contacted 440 Source today and was told they are no longer offered bare, 
so so much for not buying stuff twice.
My Edelbrock experience is with small block Ford heads, and they've always 
been fine. I've seen other SBF heads (can't remember whose) that had way too 
many shims and were thus running way too much spring pressure out of the 
box.
I agree that any heads should be checked, but I trust the quality of the 
parts used on the Edelbrocks more than the no-name stuff used on the 440 
source heads. BTW, if they go up 200-300 a pair, they'll cost almost as much 
as Edelbrocks.
