1993 Gen V 7.4 will a double rollover timing chain fit under the original timing cover?

not really sure but a single row is all thats needed. Many late model OE engines, like GM’s LS-series V8s, have a single roller timing chain. A single roller is also ideal for most high performance street engines. When you get way up in the horsepower and rpm strata where big lift cams and very high valve spring pressures come into play, a double roller chain can better control harmonic vibration at the cost of a little additional weight. That means more stable cam timing in the engine where even a little deviation can cost horsepower.

I agree. The 8.1 runs a double roller chain and I have a set left over from another build. The internet says it will and won’t. I need to find it and do a mock up.
