Does anyone have a 340 valve spring retainer the can measure? Specifically what is the OD and the OD of the first 'step?'
Are you looking ,for 340 retainers? Or springs ,to fit some.....?
Dia. "1" is 1.338, Dia "2" is .995 by .090 tall BUT this inner step is not all flat. half of it is rounded off.
