Bravo, sir, bravo! You and your reserach are, dare I say singlehandedly, promoting the propagation of enthusiasm for hardcore F series engine building at the current time.
I am happy to find this, as this supports other research done previously by others, including Wes (wed3k). Long ago, he established an account with PEP (Precision engine parts). They offer 0.5mm oversized stainless steel values and bronze valve guides.
Intake: 1.16mm head, 4.86 Overall length
Exhaust: 1.35mm head, 4.41 Overall length
Since they apparently fit in the stock seats, I'm not sure they provide much benefit on their own (no throat enlargement or re-seating) after your research. Apparently, there are other companies that were selling 0.5 mm oversized valves as well. I am sticking around for your 2 mm oversized valves and seat blending results on your PT3!
