Real world Hughes Steamroller experience?

Howards does not carry all the different grinds in stock...only a few.

Howard carries alot more of the big block grinds then the small block...
Of course I was thinking the obvious and going directly to the source for a better price. Also out of curiosity what does keep you from taking what I likely assume is one of your many spare cams and having them reground and having lifters touched up?
I could only assume that it would start messing with the geometry or you would have to get over size pushrods? I'm almost positive you don't spend money on name but on quality.
