I am make a .375 scale 4 cylinder engine and I am looking for valves that are approximately 38 mm/1.5 inch long, stem dia 2 to 2.5 mm/0.0881 inch, with a head dia of 13 mm/0.5020. These numbers are not cast in stone, and can be from any engine. Please let me know if you have such items in stock, their part numbers and cost. If not do you have any suggestion were I should try.

You help and guidance would be sincerely appreciated.

 

Part numbers don't give the dimensions on valves and a lot of other parts for that matter and most techs don't have the need or time to measure. This is right up the alley for a good machine shop that deals a lot with small engines.

 

I've seen scale engines before where all the parts were custom made with the possible exception of springs. Valves that size aren't something you're likely to find anywhere.
