Anyone build a high RPM 273 using 2.02 size head?

"Stock 273 block 8 sleeves and 3.75 bore for 292 cubic inches
Stock crank
5.4 H-beam Ford rods with EDM pin oiling
Diamond custom pistons with crappy 1/16 ring package
Wet sump oil pan and HV pump with oil crossover
Iron magnum style engine quest heads w/roller rockers, jomar girdles and pushrod oiling
Comp solid roller cam and lifters
Lots better parts today to make way more power"

On post #109 is a picture of this 273 with the very heads and rocker arm system used during the dyno runs.

Is 426ci 360 a small block?

As noted in the thread, later the heads were used on a stroker engine with bigger valves and further modifications.
