Isn't this lovely. My JWT cams are wearing abnormally. Well, only the exhaust cam is wearing. The oiling tubes are clean and clear. Tonight I am going to check to make sure oil is getting to the tube.

I seem to be down on lowend power but I think that could be the cracked header. Have you mic'd your cams to see how much wear is there? I plan to do that this week too.

Any chance these didn't go through a proper heat treatment/hardening?

Lastly, with dinosaur V8's anyways, they always recommended replacing the lifters when putting in a new cam. Did JWT recommend new rockers in case the old ones were worn?

Yea we put new rockers in as well. taking no chances.
