What Fits Under Factory Valve Covers?

I don’t care so much about that, only the savvy will recognize that. I did 20 round with the idea of making a block off plate so you can’t see the engraved , but I think if they’re painted with stock looking valve covers

Oh snaps triple R, I thought you were referring to the cast covers with the fins that have MP plastered all over them.

Nope. I can read pretty well. I saw where you said stock valve covers.
