If you're trying to be on a budget, I see no problem with the SD rods.
I would never use the cast rods if you have these available?
I had run my SD to 7000 RPM many times with the stock SD parts.
It is just that they were rare so I changed to a stroker assembly to keep the factory stuff as spares.
I also don't think there are too many flat tappet cams that would wake up the SD heads. (at least for the money)
With a roller it would last forever probably with no worries of a flat cam or other problems.
Used roller stuff could probably be found cheaply.
