looks like a new one.. flat in the are where the button rides. problem is a used one with the oe plastic button tended to wear the surface on the outer edge where the spring was leaving it convex with a point in the center . spot facing is merely grinding it back to a flat surface for the new roller button

Got so if it's not to bad I can just smooth it out and it he good for the new button .got my chain just now from Ta the v1522b.would that be the marks to line up in the pic ? This is my stock motor stock cam

If the front cover is worn as you mentioned, should it be welded and resurfaced, or simply machine it flat? My buddies is probably 1/16" work deep, point in center, going to roller cam. Hope this is alright with the OP I ask in this thread.

for 1/16th i wouldnt weld , once flat it will take a little more shim behind the button
make sure its flat (little low in center is ok ) and that the new button will fit the recess and not be riding on the outer edge preventing it from sitting flat , if not you need to spot face and widen the area so it does have a flat surface

Thank you for the answer. I appreciate it.

Yes the Webber billet Roller set up 206/206 and also it answerd my other question about my stock motor that Iam doing now in the car .

So it has to be machined if it's to bad ? Or is this ok ?this is my 100 thou cover that had the stock plastic button that I am putting back on after doing the Earl brown mod
