Here is what my head porter told me:
"The valves you need for the heads are p5027 and p5026 precision engine parts. PEP is for dealers only. You can buy direct from SI Industries though."
Please see pictures? The valve part numbers listed above can be bought through SI Industries. The intakes are 2.19, exhaust are 1.81. Please let me know if you have any other questions? Thanks, Bill
