Bartantero, it depends on what kind of style you are planning to build (chopper, custom etc.) and how much money are willing to spend...
I prefer swedish frames. The shovel-style motor is perfect

BUT, my opinion is that a Daytec frame and Shovel motor won´t match together... Like Mikira said, Evo-style motor would be better. However, that´s my opinion.

A Goldammer front end would be perfect with your combination.
I´m afraid you have to figure out yourself the style of your bike, then we´ll get back to the component level.
Take care,
