Cams for 318's

Interesting.

I thought .520 was the accepted max lift before machine work.

I have a Lunati HR cam that is .517 at 1.6 rocker ratio and thought that was pushing it.

I have a 512 lift cam in my magnum
There Is only 20 thousandth clearance between the retainer and valve guide
Completely stock except for the cam and valve springs
