Valve spring limitations vs Cam selection

Thanks Mark. I am leaning towards an Oregon regrind that was recommended by a couple of members using them and the cost savings. Plus I have a good blank. I do understand that the Lunati and Howards have MoPar friendly lobes. I also see notations on the Oregon grind sheet with cam profiles that they copy (ie XR270HR) in some cases.
Your core should also be Mopar friendly.... whether they can put a Chevy grind on your Mopar core I don't know.
