D-series valve spring question
 

I didn't have my helms manual on me when I assembled my head and I believe I put the valve springs upside down. Will it be okay, or should I take it all back apart and do it the right way? Kind of a dumb question I know.

Redo it, the tightly coiled end of the spring should be on the bottom. It's designed that way to increase spring pressure the further the valve opens to keep valves from floating at upper rpm's. You might be able to get away with them upside down, but for peace of mind it'd be best to fix it.
