Difference between Mark VIII and Cobra valve seals?
Does anyone know the difference of the valve seals between the earlier Mark VIII 93-95 B-heads and the newer 96-96 Mark/Cobra B-heads?
The heads I have were recently rebuilt and I have the suspicion that they are the older ones, but I did not know there were two types until I had the newer type valve seals installed. They originally had the older non beehive valve springs but I upgraded to Cobra beehive springs when the heads were rebuilt.
The reason I ask is it´s a totally rebuilt engine, 4.75 MMR stroker, vortech v2, and I find the oil consumption is a bit to much.
It has eaten 1.5qt of RP break in oil after about 250miles.
