Is this a good cam for my 416 stroker

They do not take the small hex head replacement plug RC12LC4?

And did the 828 roller lifters need grinding to fit & work?
Just looking to be clear.

The large 13/16 plugs won't work. There is not enough room for the plug socket. Yes you have to grind clearance for the cross bars to clear the block. You can see it in some of the first pictures.
