scarring on camshaft

[TheRealSy90]

Since it's not on a lobe and just on a head journal I would have it polished and it should work perfectly fine, there's more than enough clean area on that journal, as long as all the rocker lobes are good. Especially since it's at the back of the engine opposite of the cam gears. Maybe if it was on the cam end i'd worry about it.

Thats an excellent point. One could take a few thou off the problem areas in a lathe possibly there would be enough meat to get by. However this will cost some $$ and time. If the head journals are that rough, theres a distinct chance the cam lobes got their fair share of wear too.
Eyeball engineering on cams of a high revving engine, thats a way to lose sleep! If the new cam is only $280 thats a no brainer. I would feel like a real dumbass if I junked my head and scored up my cam journals over less than $280. The amount of limiter a peaky SR20 sees and how violent that is on cams.... Yikes!
