With 236/242 degrees at 0.050", the max lift should be around 0.485" on the intake 0.500" on the exhaust with an advertise duration of around 286/292.

If you find a cam with 230 to 236 degrees on the intake and another 6 to 10 degrees on the exhaust, then that would be good enough. But use a narrow LSA, from 105 to 107.

Advertised duration should be around 50 degrees more than the at 0.050" duration. Any less and the engine will make less power than it should and any more it risks a lobe failure. (IMHO)

Use a ZDDP additive to keep your new cam from going flat.
