Grinding, " diesel " noise under valve covers

I would just get it back rolling first.
Yessir! I'm off tomorrow, so I'll get the front end up higher and level, and try to get as good as possible toe settings, then roll er up the gas station and back. Maybe even get er to the shop up the road fer an " alignment/ toe n go" grrrrr...Thank You Rob! Hope you and Kitty are Well!
