A roller chain does not self dampen to the loading and unloading of a cam lobe as 16 valves opens and close, in fact it’s said that the added mass of the rollers themselves when not riding on either gear creates a escalation of vibrations as the rpms go up with the result that the chain beats itself up due to yet a different pitch of vibrations then the cam lobes make.
Also we have not factored in the 17th load of driving a mechanical fuel pump, nor the loading and whatever vibration pitch the oil pump adds to the mix.
The next motor I do for myself will get the duel idler gear drive I have sitting on my self even if it’s only a street motor!
