Simple way to check is pop off the oil fill cap and look. The Scorpions are a cool blue/silver color. The cranes were yellow/gold

Okay thanks, that is good to hear. I appreciate the information and your quick response. I will double check the color of the rockers just to make sure.

The 600 SCI has the smallest camshaft of the 525/600/700, so you should have no issues at all taking that engine to 200 or more hours before needing to freshen the heads.

Ok Thanks!
Maybe you can give more tipps!
I think about new valve springs as engine has not run since 7 years.Stand in warm shop 7 years conserved.
Better new springs or wait as they only 50 hours run.
Thanks.
