I may have missed it, but I didn't see the size of this engine. I assume it's a 455, by the size of the cam. To me, an intake lobe of 240° @ .050 is too big, even in a 455, for a mild to moderate 455 street build. I definitely wouldn't attempt it without Rhoads lifters.
But, after doing more lookin, I see that it is an XE284. So, the Rhoads may not be a good idea. The Rhoads, along with the steep closing ramps of the XE would probably make lots of tickin & clickin noises.

There are much better cam choices. But, I realize that the OP didn't ask for cam opinions.
