h22 all motor w/ oversize valves?

I just pulled my head apart and found out that my ferrea valves are actually 1mm oversize. I was planning on running skunk2 stage 2's with my set up but skunk recommends against oversize valves. My engine setup is
h22 block
h23 crank
h23 rods w/ arp bolts
h22 type s pistons
arp head studs
ferrea +1mm oversize valves
ferrea springs
ferrea ti retainers
type SH cams (want to swap out)
imagine engineering header
intake manifold converted to single stage
balance shaft elimanator

Any cams that work with oversize valves or should I stick with the type sh? This will be a street car that gets taken to the track every now and then. Rev limit will be about 7500. Any thoughts?

Over sized valve dont gain and even lose power according the the alaniz website.Also if you go with a very high lift cam there is a possibility that the valve will hit each other.

I have fererra 1mm oversize in my h22 right now but I'm switching them out for stock size valves, since I'm using crower stage 3 cams, and crazy high compression very soon.

stock valves are fine. you wont gain anything from going with oversize valves.

so oversize valves in h22 lose power? Is this because of a stock port not profiled to the bigger valve?
