Lunati just got into real Mopar cams. Give it time. Lol. Aren't MP cams based on stock type heads? Doesn't seem like they are compatible with today's technology. I'm no expert of course.
Mopar grinds were agressive for their time and yes they were based on head flow,they knew a stock small block head was out of steam at .450.I believe they are a good grind for their intended application but the quality is not what it was.I have installed several and all were off from where thay should have been although all were easily corrected with a multi keyway timing chain.The best thing about modern fast ramp cams besides the higher lift is their ability to build cylinder pressure due to the advanced lobe design,you can have a rougher idle,top end horsepower and low end driveability all in one package.
