valve seal replacement

I'm in the middle of a valve seal replacement and I just got the engine apart. It was a bear because of all the EFI gear I had to pull out. Now that I have the head off, I'm going to do a big clean up. But I got concerned because I realized that I don't know how the oil flows up to the head. I want to be careful to not block anything off when I clean it up. Is there a diagram anywhere that shows the oil channels? or can someone describe it to me?

Also, when I pulled the head off, all of the valves looked like they had burnt oil on them, which confirms my seals were leaking, however, the #2 (or #3) intake valve was white. Any thoughts on the cause? I really don't have any way to adjust individual fuel flows because of the EFI. Could it be caused by a hot spot due to lack of oil in the head???

Also found out an interesting fact: I'm supposed to replace my fuel lines every 2 years. I'm pretty positive that the fuel lines are original, so I'll be adding that to the shopping list.

Oh yeah, pics to come. Sorry, I'm at work (shhh, don't tell anyone). I've been taking them during the teardown.

Thanks in advance.

cool chart. thanks. I'm printing it out to look at and to put into my binder.

Thanks.

Oil usually flows up into the head through passages that have O ring seals at the cylinder-head interface. On mine, there are also metal tubes that function as restrictors to keep pressure up, but I don't know if yours has these. You definitely must replace all the O rings.

thanks for the info. I got a gasket set from Jeff and I think that the o rings are in there. I'll check.
