something around 270 advertised duration is a good compromise, without any increased compression more than this starts to make the engine a bit too soft off cam particularly the 25 6K1 engines.

i would look at schrick or dbilas for an allround daily driver, the catcams make good mid and topend power but take alot from the bottom end to do so and having measured various cams with schrick you get what the specs say on the brochure. With catcams the duration are fine but the lobe centres are usually quite a bit wider than the specs say and that is why they make top end but no lowend
