Now whats going on here!

Almost all my valves look different inside my engine and I have no clue why, some cylinders appear wet while other cylinders appear dry as a bone.

Thats the exhaust valve from #2 cylinder

Exhaust valve from #8 cylinder

One of the odd looking valves on the drivers side head

This appear to be normal IMO.


Maybe this explains why my car did so poorly in the quarter mile and dyno'd like crap?

How could this affect my performance, and whats wrong in the first place?

Looks like to me, #8 has a bad valve seal. It would also apear that more than one cylinder is running rich. Could also be valve related, as in burned/carbon build up and not sealing properly. Did you do a compression test or leak down before you pulled the heads? Why did you pull the heads?

Has the car ever run correctly since you installed the cam XE 230/236 (Highest lift) 112 LSA? Has your programming been changed for the new setup?
