small blk rocker geometry

Stock springs assembled were 1 5/8 to 1 11/16. Mine are 1.800 which is about .113 difference taller. So with that amount plus like you said about the stems not being machined down to the correct length adds up to .120 and then some. Don't feel like pulling the heads and have the valves reworked if I don't have to. I'll have to do some more research on this and get back to you and let you know what I ended up doing.
