if you’re looking to have a run of cores made, you should check with whoever is making them, as I would assume they will likely want them all to be the same...... to be able to get a price break on them.

There isn’t a whole lot of latitude on how much you can change what the basic core is made like, for your finished product.
It’s not as simple as a “firing order swap”.

If one guy wants a .425 lift 114 lsa cam, and another guy wants a .470 lift 110lsa cam..... that’s two different cores.

One core vs 10 cores....... what’s the price difference?
