yes, my cam is the cast steel type. i have had trouble with cams as i have been running the (milk can) style lifters with my cast steel cams. they are a hardend steel lifter and not compatable with the cast cam.this is probibly what you have. i'm now trying some cast steel lifters to see if that gets rid of the cam problem.as for cam grinding i've had cams done by iski, oregon cam grinding and my last cam was done at redline cams in albany oregon. very happy with redline, their a small company and will spend some time with you to get things right. they did a nice job on my cam, reground the lobes polsihed the bearing surface and parkerized it.
