I understand, but my point was the stock valve covers will clear both aftermarket rollers AND the GLM manifolds. Some taller valve covers interfere with the exhaust manifolds so I kept the stock covers to eliminate this type of fitment issue. You could install the stock covers and should be on your way. They may not be as flashy but you could get them chromed if that was important to you.
Best of luck.

I understand your frustration as I nearly had the same dilemma until I had that "a ha!" moment getting the stock covers over full roller rockers thus clearing the GLMs too.

I ran unto the same issue when I switched to Dart heads & a full roller setup with stud girdles, I ended up heating & putting a dimple in a cheap old set of covers then bought a nice set of aluminum ones from GM Performance store they fit perfect! kinda a weird shape on top but the look great a little pricey I had to buy (4) Summit Racing Part Number: NAL-12480127 good luck!

That looks about what I had hopper. I ran the 3/8 header flanges for a few months, then finally had enough money to buy two pairs of emi thunder manifold and long tails, those have plenty of room with no spacers.
