What Fits Under Factory Valve Covers?

Those would help. But curious how your gonna hide the Trickflow engravings

I don’t care so much about that, only the savvy will recognize that. I did toy around with the idea of making a block off plate so you can’t see the engraved logo, but I think if they’re painted with stock looking valve covers it will be close enough for me.
That's what I was talkin about, dork.
Oh snaps triple R, I thought you were referring to the cast covers with the fins that have MP plastered all over them.
