I suspect a .006" (instead of .004") measurement would put The SPC-8, advertised and overlap, closer to a 744. Faster ramps than a 041.
If you look at ICL @ ,004" adverised and ICL @ .050".. May even be some voodoo crap going on.
With HFT or SFT cams (make that any cam).. The same @ .050" numbers isn't enuff for me.
SPC-8 isn't a copy it's a replacement. Like a toned down more street friendly version of an 041.

The last time we checked an SPC-8 it had identical numbers at .004. .006 .020, .050. .100, .200 as an NOS RAIV cam. Maybe they changed something since then as they did with the 744 copy. I'd think almost any 230 @ .050 with the intake centerline installed around 111 would be okay with 9.9 compression ratio, premium fuel, good tune up and a decent quench. I know we have a lot of 235ish HR engines using 10.5 compression with zero issues with detonation and those usually have an ICL around 109. Aluminum heads we will run at 11:1 with zero issues and higher than that with bigger cams.
