Finally an option for f22 oversized valves!

[wed3k]

PEP (Precision engine parts) makes a .5mm OS SS valve
Intake: 1.16mm head, 4.86 Overall length (PV2565HP-C)
Exhaust: 1.35mm head, 4.41 Overall length (PV2566HP-C)

they also make titanium retainers and aftermarket 5.5mm locks but i dont know if it fits f22a.

I bought KMS 0.5 over sized valve this summer for my head project.

Are these hardened? I don't want to be worried about snapping the stem off with high spring rates

Good question. I just paired these with Bisi springs. Hopefully they'll hold up well

How would oversized valves help if you dont open up the port and use a bigger valve seat?

I'd like to see a pic of them side by side with stock valves

They wouldn't help all that much.

If you want them to perform you would definitely have to open up the seat and throat areas. You may or may not have to install new seats. .

Whether or not you need new seats depends on the outside diameter of the original seats. 0.5mm or 1mm over stock valve might be ok on the original seats.

these will fit on stock seats.
