I have an r3 engine that was purchased from stu-v products co. With r2 heads machined by them as well. I am going through the engine and in need of some help finding parts. The one I am having a hard time with is valve seals. From what I have found the heads were reworked for chevy valves. Dose anyone know what chevy valves might have been used? With the engine out is there any thing I should look for?
Some pic of engine now and when it was new any help is greatly appreciated thanks
