Looking for some lycoming part numbers

[jason crozier]

Does anyone have a good site to find lycoming part numbers. I am needing numbers for intake and exhaust valves and springs for a 0-290d2b I have searched on lycomings site but could find nothing.

Any tips would be appreciated. Thank you

Thanks T.J. Do you have any idea why they would give two or three numbers for the the same part, or are the parts different in some way.
I was maybe thing different spring tensions and maybe larger/smaller size valves? not sure about that. thanks for looking it all up for me.
