It's just a matter of selecting proper valve springs for the roller cam you may choose someday. No big deal at all. The main thing is having enough spring pressure to keep the heavier roller lifters in check.
Those round port gaskets look great. I sometimes file them open a little to make sure no part of the port is covered.
***Edit: I just posted a question at Summit asking for spring installed height, seat pressure, and rate. A 1.46" spring installed at a height that allows .550" lift would typically be stiff enough to handle 6000 RPM or more, as well as many mild roller cams. The only thing that makes sense is Edelbrock chose a soft, long travel spring for this head.
