Solid Flat Tappet on Hydraulic Cam?

Ive been looking at a bunch of different regrinds from Oregon Cams. Care to give any opinions on these?

718 209/209 405/425 114 LCA
574 221/230 419/438 110 LCA
818 212/212 431/431 110 LCA
609 20/208 462/465 107 LCA

I'd call and ask about fiddling those specs some, but that's a good cam. Those other regurgitations seem too small and not worth the lash. The heads shine @.400 -.500 lift... you lash those re grinds and you'll be in the .300s lift... with just added duration to compensate. They would work for a 4 door dart, 2 brl 318 great I'm sure...bone stock build.
