Agreed, they're really not the same as-cast.

If I already had a matched pair as-cast, I'd probably just have the guides honed, intake valves backcut, do a light cleanup like I did with my rpm heads, and would just use them.

But...as you can probably imagine, I "got a good deal" on these.

Like so many other good deals, it will cost thousands to get things
in shape in running, but that's par for the course.

Oh, speaking of..there's another topic I'll email you about in a bit.
