Another cam regrinding outfit got back to me, Bullet Cams.
Here's what this guy said:
Hello Sam,
there are 2 different size of stock cams these engines come with from the factory.
They are both small cams. We can not make a big change to the grind as the stock
Heat treat is not deep.
This is about all that will fit the stock core.
Thank you,
Chris
