Small block valve cover clearance??

Very nice but check out the bolts that come with them. I didn’t have that same brand but my bolts were really cheap looking. I went to Fastenal and bought good ones. I had to go back and edit this because with the spacers you will need new ones anyway.

That's a very good reminder, thank you.
I'll go on McMaster Carr and order new ones - probably Stainless.

Thank you!
