Hello all. I have the head off my 2 L for a few reasons. One of them is installing new cams with higher lift that required me to relieve the follower bores. After doing that I gave the head and all valve components a thorough clean. On reassembly I now have the ability to take a close look at all of the aluminum parts. So far I have two questions:
I noticed some scoring at the front of the frontmost exhaust cam shaft bearing. Any advice on this? The rest look good as do the caps.
When I rebuilt the head i used the guides which are cut for the white Teflon seals. The head has only approximately 3000 miles on it and the seals and valve stems look good. I presume there is no problem leaving the seals in place?
