Well I did a compression test and it doesn't look goo for my Holley heads...

[Rick 91GT]

Well guys/gals I have been fighting the oil consumption problem for a while but I always blamed it on my hi-volume oil pump and my Holley cam which pulls very little vacuum. Most of my cylinders hold awesome compression 175psi+ but I had 2 that were low 80psi and 110psi, I found a piece of one of the oil seals in my return hole in my heads and most of the other seals aren't in theiore seats they are positioned either all the way at the top of the valve or 3/4 of the ways there. I have to call Holley tomorrow so I can get these things returned, which should be interesting since the heads I have aren't supposed to be out till this spring and I have had them since last April, I think I got them by accident, but I called Holley when I received them and they told me these were the better heads but mine have some issues.
