I've put wet fingers of oil on cam bottom seating faces only. Would that be enough for it to go around when spun by hand. Before being torqued up.

hi mate i would just built the engine up and run it, it will bed in on its own mate
you are worrying to much

Jim you may have a point the exhaust cam may be bent hence why it has a tight spot on rotation.
I cant take a risk as it will be 3rd time i will have done the head. Im gonna strip it down and re-check it.

hi eddy. old thread so sorry. what happened with this?I am having similar issues. torqued to 23nm and tough to turn. 3 bolts in camshaft and can turn just about by hand but feels too tight. anyone observing like knobby maybd can comment on this? I had head skimmed, can't think that would affect anything but wondered if it might somehow? all the same cams etc . I feel like I could expect exhaust to be tougher as driving vacuum pump but both cams are tough . someone said about warming torque wrench up by using o tightened bolt a bit before but am wondering if torque wrench can be trusted. the first torque stage of 10nm and they turn ok but second stage 23nm and tight. I did put oil on journals .

I'm afraid "eddy" hasn't been on the forum since November of 2018...so you may never know what happened with his.
Are your cam carrier and cyl head a matched set, originals?? They are "line bored" as a pair at the factory. If "torqued correctly in the correct sequence" and you can turn the cams by hand, they should be ok....if the cams lock up totally, you'll have issues.

and did you do it in the correct order

did you lube it up before fitting the cams in to the carrier.
i have done these engines many many times and had the same problem with some of them and never had a problem with them once they are running it will bed in to the cam carrier
i have even bought a brand new cylinder head and used all the old components from old head and that ran great
