I was re reading your first port and that ratio is high for Cali. 91 & the cam is on the small side. I’m not sure I’d run that no mater who said I could. It’s just to close for me.
To suggest a cam without getting into the science of it all, another 10*’s duration would be about right. As also asked/suggested, a solid roller would also help due to the way there ground and act. I know it is expensive.
Perhaps a stout solid cam would be the best middle ground. Also might as well get it with an amount of lift generous enough to take advantage of the heads cfm flow ability.
