Just the ones that came with the Felpro set. Each about 3/16. (probably your .197.) With the 2 under it, it almost clears.
I just ordered these: https://www.amazon.com/gp/product/B000CMD7I8/?tag=joeychgo-20 They're supposed to be "tall", and maybe because they're stamped, there will be a little extra room. Not too expensive, and my Edelbrocks are ugggglee. That's the way they were when I bought an entire wrecked D150 for the drivetrain. I spent about 4 hours polishing one (still needs more) before I found out it wouldn't fit. DOH!!
