Someone might give you a straight up answer but I looked at mine and it looks like you could go maybe 3/4 to 1 inch taller than stock center bolt covers. How much taller than stock are they?

They will NOT clear the normal squared edge ones. I used them on a vortec stroker motor I built for my previous boat. You can also get a steel spacer for the manifolds and use tall fabricated ones that have slight angle to the edges. Spectra performance sells a decent set of fabbed vented bolt ones that I used.

As said above, they will NOT fit, I tried thicker gaskets didnt work, ordered a set of 1" spacer thought that might work it only made the problem worse. FYI if you need a set of spacers I have a brand new set & two brand new sets of super nice tall square aluminum 3/8 flange valve covers haha......

I used retro style Edelbrock finned tall cast covers. I had to heat and gently clearance the covers with a curved body dolly. They clear the risers and Comp pro-magnum rockers, and I can remove the covers without issues.
