Comp springs recommended are 926-16 or an upgrade duel spring 924-16

Top guides,
Cut spring seats for cups

Single pattern cam is not appropriate for a BBF and will cost you 25+ hp on the top side.

Okay, thank you so far. Is it possible to identify the installed Springs?

I bought that Stuff in a bundle and maybe the Springs are already others. Not Sure about my Engine Guy here in Germany knows what to Do when i Tell him to cut Spring Seats for Cups.

This is how they looked with removed Springs.

Here's a little valve stem seal trick I found, Use early Small block Chevy valve seals for a LT1 engine (Corvette/Z-28). The rubber seals are smaller then the standard ones due to Chevy loving dual springs in their engines and so they used smaller seals. They're also the same stem size as the all Ford engines except the FEs. The FEs use the one for the BBC LS6 engines. That way you don't have to cut the head stems.

Ok i guess i found it out myself. The Degrees of the Locks Depends on the Retainers and i just have to watch out for the right Valve Stem Diameter. Guess theres no height Differences on the Locks right?

There is, watch for ones that are - or + and standard height.
