Jets & Power Valves

I dis assembled a couple 97’s recently and found that neither the jets or the power valves had numbers on them. Is this normal? Is it just assumed that the sizes will be known if original?

Does anybody know of a good source for these parts? I mean quality parts, probably original or NOS parts, not Chinese crap. I have had some problems with “new” power valves.
 
Use only genuine Stromberg parts. Jets and power valves should have numbers stamped on them.
What problems have you with "new" power valves?

Sorry, I’m at work so not sitting in front of my computer. I have had multiple experiences of power valves that don’t close completely so the motor runs very rich. These have been aftermarket valves that were part of kits from Speedway etc. If you sell the parts I want then I guess my question has been answered. I am in the process of building a pretty hot “B” motor and have not decided which downdraft or downdraft(s) I am going to use yet but I am going to be looking for some advice re jet and power valve sizes to use for the application. On the table right now for consideration are (1) 97, (1) 48, (2) 97’s, or (2) 81’s. I have all the carbs I just need to decide which way I’m going to go.
