intake valve help

I am looking for a set of 1.94 valves with a 5/16 stem, and 5.01 overall length. Anyone else had to find these? I've searched and can only find a set from Manley that are 180 for the set. I'm near the end of my build and the budget is drying up so any help is appreciated

I heard that you can use very inexpensive 11/32" Chevy valves. The machine shop just grinds the ends down to the correct length anyway. Chevy valves are almost free. If your guides are already machined then it might not be worth it.
